I also got a couple of shipping expense surprises with them as well. Mostly stood out as it was a separate transaction on the CC. For the stuff I bought, their pricing was much lower than anyone else, I was still money ahead. Somewhat hypothetical, as it's hard to shop around these days.
$34.49/box for Hornady 147 ELD-M sure looks attractive these days. There's some 143's for sale right now, on here, for $65/box delivered. That would make shipping $60 vs. the $16 you paid (I'm giving the 143's a value of $35/box).
The separate shipping charge was about $16 for me as well (on 500 bullets, so $3/box). For me, the shipping cost was basically the same as I'd pay in Idaho sales tax (6%), if I bought local. Not that there's any inventory around here and the truck just burns through that expensive diesel.
