Okay. Here's what I do. Takes about an hour on the outside for 15 items. First get adhesive label sheets. I print all my labels together. As I'm printing them, I record who bought what. I go box things up, usually in the order the labels are stacked. I bag and box everything. Thie single thing that will save you the most time is the adhesive labels.
Seems about right. It took 90 minutes to ship 22 items today.
