The interest is deferred. These plans (usually offered through companies like American General or GE) have interest based upon original purchase price from the date of purchase if not paid off in full before the anniversary date. Most times when you participate in one of these, it is spelled out on your monthly statement what the "deferred interest" is.Keep in mind the interest is probably deferred. The interest is accumulating based on the average balance during the promotional period.
DUI is willing to take this interest float for you to get you in their products
Remember - DUI isn't financing these products themselves. They are "hiring" American General to do it. You won't get a statement from DUI, but rather American General.

Same as Cash promotions are great - IF you pay them off in the period specified. If you go beyond the anniversary date, you will get HOSED! My last home theater purchase, I did 12 months same as cash. I paid it off in 11 months just to play it safe. 1 day past the anniversary date can cause them to bill you for a crap load of interest. So purchase wisely!
Allowing people access to the program is a great marketing concept from DUI. I would venture a guess that other equipment manufacters will be following suit (no pun intended)
