Best cnfans sheets practices for intermediate users

Hey everyone, I've been using cnfans for about 18 months now and wanted to share my experience with their sheets 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 sheets aspect is actually quite useful once you get the hang of it. I've ordered 69 items so far, and only had 2 issue that customer service helped resolve within 15 days. If anyone has questions, feel free to ask. I'm happy to help fellow shoppers avoid the mistakes I made.
