Ah righto mate I hadnt considered the set up costs, then theres VAT and shipping etc. soon adds up, specially if u import from across the pond...
I think the best thing to do is buy a set of normal jerseys, say Dye C5 jerseys, and then get them printed (Dye even do it for you). That way you get top quality matching jerseys with your own personal artwork on them.
We got our blue proto jerseys printed with our logo and our names etc all for a very reasonable price and (I think) they look pretty good
