Experience with Adio Equipment Trade-Up Promotions

The plus of a trade in. If you have State Sales tax, the value of the trade in is no sales tax on that portion.   No hassle. they take it and you are done. Selling it yourself can involve a long wait, fraud, a buyer who claims it was broken and demands to return it.THe main plus side of selling it yourself is you can wait to sell. Suppose the new gizmo sucks? Now you got rid of the of the old one you really liked. AND have a boat anchor. If you did not sell/get rid of the old one. at least you can still use it while figuring out how to get rid of the new one.           
I have been very sad I stupidly sold /traded in my old well like item, and got a really bad steaming pile. More than one I am afraid. (in my youth (30's) is the excuse)

Any trade in will be less than what the item could sell for on an open market. Obviously, it takes more time, effort, and likely some expense to get that best price when selling. Only you can decide if the extra is worth it.

Thanks for all the input and perspective guys. Clearly it wont hurt to see what they offer for my used trade-in and I can assess and go from there.  I do highly value avoiding the hassle of listing, shipping, and dealing with an unknown 3rd party so I'm certainly willing to price that aspect in.
