I received your mail order info letter, but I have a question. You listed shipping rates using UPS rates (I discovered this since only UPS has the name "2nd day air"). The delivery address would be to my home and I am not at home during the day. Could I provide you with instructions for UPS delivery? The instruction I need to include is: Please leave the package at the rear door under the overhang. If no such instruction can be provided, then could I use USPS instead? Thanks a lot.
