I have had a chance to read plenty of the positives and negatives with regard to shopping online. I had problems with Ebay pro shops too with bowling balls and bowling shoes.
I tried BowlingGods.com about a year ago and haven't needed to look anywhere else since. When I needed a particular bowling ball spec, they have either sent what I wanted or contacted me with options to get as close to what I need.
I have purchased 8 balls from them and have had nothing but good experiences. You should give it a shot, they have a bunch of clearance items going on right now. I just got a Dynothane Element AU79 for $90 bucks!
My $.02,
