i've been sending quilts all across the country for a few years now- i always use priority flat rate (when they fit) or regular priority mail boxes if too large for a flat rate. i ALWAYS add insurance & delivery confirmation...the one time i did not add insurance/delivery- because the customer insisted it was not necessary-- i sent quilt in october---she finally received it in March---for 6 months she was upset with me- and saying very negative things- i had no way to track it- because she insisted it was not necessary- when she finally received it & with it the explanation/apology from her post office she was very...sweet to me, apologizing, but alot of damage & hurt feelings had happened in the mean time...so i ALWAYS regardless of what someone may say- ALWAYS add both- insurance & delivery-and have never had one take longer than 5 days to get anywhere- usually 3 days is all it takes.
