I would absolutely contact them (I had to this morning and they were awesome..didn't make me call back and took care of my questions right then and there; it related to layaway). I am not sure if they will but you absolutely can put any eligible item on layaway that you want. I've done that 2 times lately and love it.

Probably not if not listed in special deals or manufacturer rebates. Unless it was a special code that was released by Sootch00 and approved by Budsgunshop. As for the layaway program, here it is below

I think it would be great to see you doing Buds reviews. Call them and try, 1-859-368-0371. I know they've partnered with Hickock on things before.
