I actually picked up a restaurant ecommerce that I completed and got paid for and a retail ecommerce shop where I didn't get paid. Both had a $10 fee and either $15 (food) or $20 (retail) reimbursement.
For the retail shop, first I couldn't find anything that was available for purchase online with curbside pickup anywhere near the reimbursement price. I kept getting, not available for online purchase when I'd select an item like socks, underwear, hats, gloves and t-shirts.
Secondly, when I tried to open up an online account, the store's website would not accept my information. The report has a question along the lines of "Were you able to open an online account?" I answered "no" and the rest of the report went away. I submitted the report figuring I would get the shop pay of $10.
The reply:
"Reviewer comments: This shop has been excluded without pay since you did not setup an retailer account as required."
