I tried it out by putting 3 things in the shopping cart, and it worked for me. It just added the handling fee for each item.
I have been having CS charge double when people buy multiples. These items are extremely lightweight. One foreign buyer was charged over $16 for very lightweight jewelry. It should have been $8. The buyer took some time to purchase the second item, maybe it doesn't recognize that it is a second item. Or maybe they did each of the transactions separately.
I would like to try what you said here--
"Or, you can put the boxes and envelopes you use in Package Preferences and put a shipping and handling fee there. Fees put on there go on once per box or envelope - not each item."
Can you direct me to the page I need to do this?
I changed the height to 1", it would not let me make it larger than the length. Does that sound good?
I don't need the height too high since I do not use boxes in my bubble envelope, just wrap the item with bubble wrap and gift paper. My bubble envelope is 7" x 5", a custom size, not any Etsy size, but large enough for 2-3 jewelry items.
