I use UPS almost exclusively as well, for several reasons: you can insure the shipment for its full value, the tracking is 100x better that that available through USPS, and they’ll pick up. If cost isn’t an issue, I’m happy to ship things USPS, but, especially with very expensive stationery, the fact that it’s insured and trackable is worth the extra cost for the customer’s peace of mind. It would be nice if vendors asked your preference for smaller things, like cuts, but I suspect that, with their volume of sales, it’s easier and more cost-effective for them not to give shipping options. Hopefully, that extra cost they charge you is included in the project estimate, so you don’t wind up paying extra out-of-pocket.
