I used to do that for shirts until it was impossible (I think) to buy one without the sponsor. I don't think I ever had Bovis on a Latics shirt even when it looked weird without the sponsor on the "Celtic" green one...
I used to buy them all and collect them but nowadays the inlaws tend to buy them me for Xmas/Birthday pressies.
(In the unlikely event any of them are reading this, there's a new onecoming out soon, hint, hint... )
