I guess I'm surprised that people who are cruising T-shirt sites would
get offended or upset when they are asked to create an account.
but you learn something odd every day, eh?
surveying the people here:
if you are giving Best-Practice Tips to someone building a new e-commerce T-shirt website ... do you
1) tell them to omit the Create Account option?
2) tell them to include the Create Account option?
Assuming they are selling standard phrase- or art-related tees.
I'd suggest (2) ... imho, the pros outweigh the cons.
