I love getting packages in the mail (and UPS, Fedex, etc) since a lot of them are parts for projects. Mouser, Digikey, ebay, etc.
While the parts are not very exciting it is important to continue to fill out the parts bins as time/money permits. When you decide to work on a project is handy to have the parts on hand vs. waiting 3-5 days for another parts shipment.
