Maybe I am just hurting myself...(or I'm the savior of my checkbook, one of the two), but I won't click "buy" unless I can put my entire order in one shipment.
I've cancelled SO MANY Midway orders because they don't have something in stock that I need, it ain't even funny. I end up comparison shopping CTD, Graf's, Brownells, Numrich and other places not necessarily for the best price, but just to have everything I want in stock.
Sometimes it takes 3-4 months of checking to get an order I need.
I dunno... for me, "customer service" means first and foremost having something to sell me that I actually want. Shipping is an interaction between me and UPS/Fedex/USPS more than the vendor, and any other CS element is mostly just some impersonal web form.
Just sell me what I want.
I'm glad the SS-Hoochymama is back out plying the coastal waters, protecting us from pirates, though.
