T-Shirt Printing for adults

[BottleOfRum]

My DP is the best man for a stag weekend in a couple of weeks, and he wants to get t-shirts printed for all the stags (approx 15 of them) with the england football team logo (will be away during world cup), and stag's name etc on back of shirt.

DP is utterly useless at any sort of organisational skills, and I fear he will get ripped off massively! Does anyone know any good value tshirt priniting companies online, so I can have a look into prices etc?

TIA.
