Not sure if this would be worthwhile or how many players even use speed boosts, but I'd definitely use it.
What I'm suggesting is an option to buy more than one at a time, so similar to putter pal. An option to maybe buy up to 5 at a time? I usually buy 3 or 4 at a time and it would save a little time and maybe even a couple of credits should WGT decide to discount "bulk" sales.
Thanks
