Well, I guess I operate a little like Rick does. I package and weigh each item before I list it, include $2.00 handling fee and the calculator does the rest. That way, we don't run the risk of cheating anyone, including myself. I found out when I first started this, that if I underestimated the weight, which needs to including the shipping materials, I lost money. We have eaten a few mistakes from days past. Ebay also has a policy that you can't charge more than the calculator shows. We also combine shipping and our customers seem to appreciate the savings and seems to have encouraged repeat business. We weight it up when they are finished shopping, add $2.00, insurance when necessary and we're done. Kind of simple. I have found that sometimes the UPS shipping is different that what I thought it should be - not sure why.
I think it's a crap shoot whether people hit the report button. Some people don't have a life and are just prone to do that. That's what the block bidders list is for.
Good luck to all. Hate to see it made even more difficult.
