protege garage seems pretty competitive. i don't think you'll find any place that sells brand new quality parts insanely cheaper than another vendor out there. they'll all be around the same price.
i wouldn't go that far, and i for one won't buy performance parts on e-bay from an ebay store, but from some other person who doesn't have a need for it any more possibly... also ebay is great for lil cosm mods... such as a shorty ant, shifter knobs, axela emblems, dash trim that sort of thing... its e-bay try not to expect the world and you shouldn't be dissapointed... always use the "you get what you pay for" rule of thumb and try not to laugh to hard at some of the idiotic shiat on there....
"I want quality but I am to damn cheap to pay for it"
when buying car stuff, general rule of thumb is you get what you pay for
and if you have found a cheaper/better place than Mazda3online/protegegarage why ask and why not buy from the "other" guy?
what parts are you looking for? how am I expensive? also, I'm the only place on the internet that offers free shipping on practically everything. i will admit there are some places that offer some things cheaper but those places are few and far between. most of my direct mazda competition is equal to or more expensive.
i frankly don't consider ebay to be competition. you pretty much take chances there of running across bad/used parts, bad sellers or both. some of those auctions may seem cheap but they love to turn around and hit you with exorbitant shipping charges and bogus insurance fees.
i also pricematch with the competition if and whenever possible. you show me a cheaper price and i will always try my best to match it or beat it.
