I really don't get the problem with companies NOT wanting to send out stickers to punters. Quite a few of them don't get used properly, are sold to mates or people on ebay who then go and use them on bats that weren't made by the same company.
The bat a company makes is it's shop window, people playing see them being used and might never have heard of the company itself until someone else is using one. A batmaker has control over their own output and if they have good QC checking wouldn't let a dud bat outside of the workshop.
If someone puts said stickers onto another brand's bat that doesn't perform or even worse breaks in a game, then that company's reputation might get a real hit and they haven't had anything to do with that bat..
Totally behind this. If you want to keep the original stickers either rufurb the bat yourself and sand around them, or send them back to the original maker. The prices of some batmakers refurbs are a bit ridiculous for a cleanup, but you pay's your money you takes your choice.
