Went to buy some carpet shampoo and a floor tool for my shampooer and noticed they are offering a $99 discount.
Doesn't seem to be a minimum spend as it worked on a $20 item, you just have to pay for shipping.
Bought $101.91 worth of stuff and was charged only $2.91 + $12.50: https://goo.gl/vbyXN3
EDIT: Seems you can do it more than once, just did a couple of separate $120 orders and still got the discount on each.
They must really love dogs.
haha this is incredible, just got that $99 vacuum for free. I think you can keep using it?
