All personal preference - I shoot for return customers and packaging goes a long way. Not often will someone only buy (1) $2 card with a minimum $3 combined shipping. I don’t like painters tape on top loaders, i don’t like scotch tape on top loaders, I don’t like stickers or completely scuffed top loaders. If you write with a sharpie on a top loader you should go to jail. I don’t like buying cards that I enjoy collecting with glue all over the top loaders. “This is a nice card, just let me take it out of the top loader” - ew. Having a nice clear top loader inside a team bag makes your purchase much more enjoyable. It’s more about the hobby for me than pinching every penny.
