Why do you guys deal with that? Do you not have a local comic shop in your area?
Yep, but my comics cost about half as much going through DCBS compared to using my LCS. If you look at an order I had about a month ago as an example, with what a paid vs cost at LCS ....
AMAZING SPIDER-MAN #693 - $2.39 - $3.99

Shipping - $6.50 - 0
----------------------
Totals - DCBS = $75.17 (with shipping ... monthly) Vs. LCS = $128.33 - Equates to a $53.16 in savings. I can wait an extra week for $50 a month in savings.

And it is not the fault of DCBS when Diamond holds PREVIEWS back. Plus, DCBS gives is the option to wait a week or ship it anyway.
