Have you ever searched online for a K-Beauty product and compared prices on different sites before buying it?
When you find the same product on several platforms, it’s natural to look at the price shown on the page first. But watch out: the product price doesn’t always match the final price you’ll pay. Shipping costs, duties and the conditions for getting free shipping can all change the total amount.
That’s why, if you want to know where it really pays to buy a K-Beauty product, comparing the product price alone isn’t enough. In this article we’ll compare Piyonna, Shop Y and Shop O using the same product as a reference, WellDerma PDRN Exosome Hydrating Gel Mist 100ml, and we’ll compare the product price, the shipping conditions and the final cost.
So, which site really pays off for buying the WellDerma PDRN Exosome Hydrating Gel Mist?
How much does the WellDerma PDRN Exosome Hydrating Gel Mist cost on different sites?

We compared the price of the same WellDerma PDRN Exosome Hydrating Gel Mist 100ml on Piyonna, Shop Y and Shop O. All three sites sell the same 100ml product, but the price shown on the product page is different.
| Retailer | Product price | Size |
|---|---|---|
| Piyonna | €21.00 | 100ml |
| Shop Y | €18.95 | 100ml |
| Shop O | €20.83 | 100ml |
If we only look at the product price, Shop Y is the cheapest at €18.95, followed by Shop O at €20.83 and Piyonna at €21.00.
But can we really say that Shop Y is the most affordable choice?
Not necessarily. When you buy, in fact, besides the product price you also need to consider the threshold for free shipping and any shipping costs, which can change the final price.
To understand where it really pays to buy the product, let’s look at how the shipping conditions differ across the three sites.
What’s the threshold for free shipping?
Even if the product price is slightly lower, shipping costs can be added if you don’t reach the free-shipping threshold.
That’s why the free-shipping threshold is another thing to check when you compare the real cost of a purchase.
| Retailer | Free-shipping threshold | Estimated delivery time |
|---|---|---|
| Piyonna | Orders from €20 | 7–15 business days |
| Shop Y | Orders from €45 | 10–15 business days |
| Shop O | Orders from US$60 | about 15 business days |
The WellDerma PDRN Exosome Hydrating Gel Mist costs €21.00 on Piyonna, so it’s already over the €20 threshold.
This means that, buying just one product, shipping on Piyonna is free.
On Shop Y, however, you need to reach €45, while on Shop O the threshold is US$60.
In other words, even though Shop Y has the lowest product price, if you buy a single item free shipping doesn’t apply.
So how much does the price change once shipping costs are added?
How much does shipping cost on the different sites?
To make the comparison more concrete, let’s consider buying one 100ml bottle delivered to Italy.
| Retailer | Shipping costs |
|---|---|
| Piyonna |
Free (€4.90 for orders under €20) |
| Shop Y | €4.60 |
| Shop O | about €23.74 |
On Piyonna, the product costs €21.00 and so goes over the €20 threshold: shipping is free.
If the order is under €20, on the other hand, €4.90 in shipping costs is applied.
On Shop Y, for this order, shipping costs €4.60.
On Shop O, however, the shipping costs shown for this order come to about €23.74.
At this point, the comparison is already starting to change.
Shop Y had the lowest product price, but once shipping costs are added, the gap with Piyonna narrows.
But it’s not over yet. 👀
There’s one more cost to check before deciding: are duties and VAT already included, or are they added at checkout?
Are duties and VAT included in the final price?
As well as shipping costs, it’s important to check whether duties and VAT are already included or charged separately.
| Retailer | Duties and VAT |
|---|---|
| Piyonna | No extra cost (included in the price) |
| Shop Y | No extra cost (VAT included) |
| Shop O | about €13.48 |
On Piyonna, duties and VAT are included in the product price, so there are no extra costs.
Shop Y also states that, for orders shipped to the EU, VAT is already included in the price, so it isn’t charged again on delivery.
On Shop O, however, for orders shipped to the EU, Duties and Taxes are calculated separately at checkout.
In our case, at payment we saw an extra cost of €13.48.
So when you buy K-Beauty from abroad, checking the product price isn’t enough: shipping and taxes can also completely change the total.
At this point, how much would you really pay?
Which site is the most affordable in the end?
Now we can add up all the costs and compare the final amount to pay.

| Retailer | Product price | Shipping | Duties and VAT | Final total |
|---|---|---|---|---|
| Piyonna | €21.00 | Free | Included | €21.00 |
| Shop Y | €18.95 | €4.60 | Included | €23.55 |
| Shop O | €20.83 | about €23.74 | €13.48 | €58.05 |
And here’s the interesting part: the final result is very different from what it looked like when we only checked the product price.
At first, Shop Y seemed the most affordable choice at €18.95.
But once shipping costs, duties and taxes are taken into account, the result changes:
- Piyonna → €21.00
- Shop Y → €23.55
- Shop O → €58.05
So, where does it really pay to buy the WellDerma PDRN Exosome Hydrating Gel Mist?
In the end, among the three sites we compared, Piyonna turned out to be the most affordable place to buy the WellDerma PDRN Exosome Hydrating Gel Mist 100ml.

Piyonna’s product price wasn’t the lowest of all. However, thanks to free shipping from €20 and duties and VAT being included in the price, its final total came out the lowest.
This comparison shows why, when you buy K-Beauty online, it doesn’t pay to stop at the price shown on the product page.
Before you buy, always check the product price, shipping costs and any taxes.
In the end, even a difference of a few euros in the starting price can change the result. 💡
