How to use oopbuy spreadsheet effectively (complete guide)

Hey everyone, I've been using oopbuy for about 19 months now and wanted to share my experience with their spreadsheet 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 spreadsheet aspect is actually quite useful once you get the hang of it. I've ordered 7 items so far, and only had 1 issue that customer service helped resolve within 8 days. If anyone has questions, feel free to ask. I'm happy to help fellow shoppers avoid the mistakes I made.
