How many cards do you ship ESE?
I am selling some cheaper lots, most are 2-6 cards. Getting asked to lower the price of shipping but I charge a flat rate $4.99 for USPS ground and cover the rest out of pocket. I know eBay has a trading card kit that can hold up to 24 cards and still ship ESE, but right now I’m using the same sturdier envelope as them but not the insert they customized. Do you go over 2 cards for an eBay Standard Envelope (ESE)? If you use or have used eBay Standard Envelope trading card kit to ship eBay Standard Envelope is it worth that ~$2 per kit cost to be able to ship eBay Standard Envelope?
Thanks for your help. Was shutting the store down, now have too much loose product to do so yet, so any advice so I can move the rest of my listings would be great!
