But other kinds of retailers are finally catching on, and they're being lauded for expanding the concept of using samples to entice commitment-phobic consumers. A Mercedes is one thing, but a fine wine? Here are some new things to try before you buy.

Appliances Shoppers at select Maytag outlets can use major appliances in the store to see if the spin cycle suits them. They can pop a roast in an oven or check the rinsing action on a dishwasher. Bring your dirty laundry, and you can, at the very least, finish a chore.
