I guess the problem I have with eBay and trdparts4u is that they use flat rates for their shipping. To prove my point:
Tacoma Seat Covers
trdparts4u: $152.95 (great price) + $20 shipping! = $172.95
toyotapart: $159.25 + $9.94 shipping based on my zip code = $169.19
I like the fact that toyotapart charges by where they are shipping to. Not posting a price point on a product, getting everyone to say "wow they have the lowest prices by far" and then make up for their losses on flat-rate, over-priced shipping. Same thing with most "Buy It Now" eBay sellers.
