I shall do market research of relative costs, as I am a cheapskate.
So far I know:
Sports Direct:
Shirt: £20
Printing: £4 p/number, £1 p/letter
NUFC Store:
Shirt: £25
Printing: £10 when shirt bought at same time, else £15.
JJB:
Shirt: £25
Printing: £10 when shirt bought at same time, else DUNNO
Is there anywhere else that even sells sportsy s*** anymore??!
