United Megastore strikes again. Got mine there too. This is the second time in a row i've had a problem with them. Air bubbles all through the numbers last time I had to send that one back.
Found this today on the other sleeve.
United megastore, along with barcelona's online store, and others,, is just Kitbag.com, at least if you're ordering from the US. Kitbag probably operates several other big team online stores in Europe, again, if you're ordering from outside Europe. I think if you live in Europe and order, the teams supply the merchandise through their own club stores.
The way you can tell it's Kitbag is by looking at how the store is formatted- for example, the layout and wording for customizing a jersey is exactly the same between sites, down to the "no return" disclaimer. The prices actually can be different between the team store front and kitbag' main site, interestingly, based on different promotions. As another example, Arsenal's online "USA store" is just worldsoccershop.
Anyway, wrt to your defective jersey, I also had a bad experience with kitbag (through the Official Barcelona site). I'm always wary of ordering customized jerseys online, particularly late in the season, because it's possible they might just use a previously returned blank jersey to customize and send to you. It's an easy way to get rid of returned stock. There's no real way you would know because the jersey would have to be removed from its factory bag to print the name/number anyway. Usually you get the printed jersey in the opened factory bag, but that bag could still have been previously returned too with the jersey. If the jersey is defective, I especially suspect it could be a return. Or it could just be horrible carelessness with operating the heat press or something else. Either way a bad experience and I'll never order a customization from kitbag again.
