Scotch tape is an intregal part of mailing cards and making sure they get to the other trader undamaged. Top loaders are also part of the process. Both of these add COST to trading.
Here is one way to save $$$ when trading...
SAVE THE TOP LOADER
I went through all my toploaders this weekend while making several trades. I can not believe how many of these I threw out because they were all sticky from excess tape on the edges and they were just all stuck together from residue. I have been using the following method for years without any mishaps. It saves on trading expenses which is a pet peeve of mine as postage rates go higher.
Here goes:

Sure, you may still need a piece of tape to keep the top loader from moving around in the envelope, maybe not in a bubble mailer, but don't place the piece of tape at the top of the top loader were the card can get ruined by a piece of tape as it comes out of the top loader. Use common sense.
I hope this helps and cuts back on trading costs for you.
