Never use UPS for supplies for shipping. They can be gotten free from everywhere. Dollar stores will save stuff for you, office supply places, etc. Also, since you have been shipping USPS you obviously found out UPS, FedEx and DHL are more cost effective with higher weight packages. You could have used a padded envelope for the tarts or a USPS flat rate envelope stuffed with some peanuts. When worse comes to worse, use priority mail boxes turned inside out if the size is right to send with another service. No one cares nor will know. No need for wrapping with craft paper, another unneeded expense.
