This is great, but the prices aren't accurate for the products listed. As an example, I filtered by the cheapest 64GB model, clicked on the link, and found that to actually get the 64GB it was multiple times the cost listed on the site. This was because if ebay's "variant" option, which is often misused by vendors.

I don't know if the ebay API allows you to check for variants to ensure that the price you are listing is the price for the actual variant listed or not?
