Thanks for suggesting I'm wasting client's money. UPS Ground is $6.87, Priorty Mail with Tracking is $7.71, for local delivery but (a) they removed the UPS box from my office complex (not enough packages to warrant it) and (b) USPS gives me free Tyvex envelopes. You have to use your own envelopes for UPS. So I'm not wasting anyone's money, I'm wasting time answering how I run my practice.
