My MIL was telling me about how she bought rain barrels on Amazon. I was like... really? She said they were cheaper then what she could find in town. Amazon is awesome.
HoneySpider - I would just take a look at the description and shipping info on the product. If it says it's Prime eligible with free returns, there won't be a surcharge from Amazon. UPS/FedEx may have a pick-up charge to return it, though.
I order 30-lb bags of dog food once a month from Amazon, and I love it. Furniture would be so great to have delivered with free shipping (provided it was good quality).
