In sending a pkg via UPS NEVER put "card" as description. Put "documents".
I am convinced an employee thought there would be cash in a birthday card and took the pkg. They were correct. I did not have a receipt for the $100 gift card and I had paid cash so they will not reimburse me for the gift card, only for shipping cost. I'm pissed at UPS and at myself for being so naive.
No UPS employee would take documents.
By the way, they charged $31 to ship the envelope! I was willing to pay to have it arrive on her birthday.
