fyi...

I have been to a couple audio stores across ohio, and into pa which asked if I wanted to demo something in my system...
I inquired about the process at two locations and the process was the same...

they put a hold on my credit card for the amount of the item... that is... I sign a credit card statement just like a bill, but, the money is not actually charged, a "hold" is placed on the amount of money,...
e.g. If i have a $5k credit limit, and a hold is placed for a $1k sub, my credit limit is now only $4k...

I can keep the unit for a week or two, then if I want the unit, I call in, and tell them to bill me... in which case the $1k would be billed to my credit card, or if I don't want the unit, I simply return it... nothing is ever billed to me...

not all stores may be like this... but one in canton ohio and one in columbus ohio are like this...

(I have not checked the process at other stores)

hope this helps,
Mike

edit... the columbus store's item I was discussing was ~$700 2ch amp...
