You say that commissions average 5%, but what is the variability and where does it come from?
Last, a bit of feedback about the product.
I tried searching "nintendo switch 2" on your homepage and the results that came up kind of sketched me out. You mention that the products are US-only, but the first result clearly says "hong kong" in the title. And the store listed is "My Nintendo Store PT"; is that the official store? When I google that it takes me to the Portuguese version of the nintendo website, and that makes me even more confused.
The second result for the same search appears to be a dress, which is obviously completely unrelated to video games in general.
EDIT: I'm noticing irrelevant results for many queries. Searching "plain white pillowcase", the third result is a t-shirt, the seventh result is a dress, and the eleventh result is a light bulb.
Searching "men's wallet" the very first result is an outdoor picnic table.
