My LDS runs about 15-20 bucks more on "High dollar" items. But for the most part by the time I pay for shipping if I purchase online they are pretty much even. I usually only buy online, when there is something that catches my eye that my LDS does not carry.
I do try and support them with my purchases the majority of the time. But take for instance...I'm in the market for a wetsuit. ST has what I want. My LDS does not. The closest thing they have is 40.00 more than what I've spotted here. Times like this....ST gets my cash
