Had my 1st screw-up with my t-shirt business today. Since I sell them on 2 different sites (LakasProject.com & PinoyTattoos.com), I was also using 2 different shopping carts. Going forward, I will use E-Junkie.com as the credit card processor and inventory system of record. The shopping cart has been pretty much flawless since I started using it for my Baybayin transliteration service.

I emailed my customer advising him of my screw-up and offered him a discount when the new shirts come in at the end of the month. He was cool with it.
