Quick oopbuy qc question from a new user

Hey everyone, I've been using oopbuy for about 12 months now and wanted to share my experience with their qc feature. I started off completely clueless about how things work, but after some trial and error, I figured out the process. For anyone new, here's what I learned: First, make sure you understand the shipping calculations before placing orders. I made the mistake of not checking this and ended up paying more than expected. The qc aspect is actually quite useful once you get the hang of it. I've ordered 90 items so far, and only had 1 issue that customer service helped resolve within 25 days. If anyone has questions, feel free to ask. I'm happy to help fellow shoppers avoid the mistakes I made.
