Dropshipping

Is this form of dropshipping allowed:

I advertise the product of a supplier with a 20% increase in price on my store. All products on my store have the same percentage increase from the wholesale price. I consider the 20% as the commission I receive. This has not been communicated with the suppliers, as there are many suppliers whose products are being advertised on my store.

When a customer places an order, the product is shipped directly to them. The customer pays shipping fee. They are informed that I purchase the product on their behalf and take a commission, but may not know who exactly the supplier is, or how much commission is taken (they just see total price after commission added).
