A good rule of thumb here: if the orders are being placed on the end consumers' accounts, retailers are okay with using affiliate. If you're placing the orders on your own account, they're not okay with it. Exact policies vary from retailer to retailer.
I would use priceyak significantly more if they supported the following features:
1. Support more sites. I need staples, bestbuy, and sears mainly for now.
2. Add ability to collect portal cashback, customizable to select the highest paying one at the time of purchase. Track whether purchases got the cashback and provide a list of ones that didn't so they can be reported to the portal.
3. Ability to place orders using gift cards uploaded by the user. Related: use store points (like sears shop your way points) if available.
4. Support product limits per account, so e.g. if a product can only be ordered 3 times on an account, automatically order from the next account if more than 3 sell.
5. Support listing on Amazon and fulfilling using retailers. Right now priceyak only supports eBay listing.
I'm considering building something like this myself, but I don't have much interest in actually running it, I just want something that works. If priceyak had something like that I'd use them instead of rolling my own.
