I bought a pair of ugg boots at Rivers for $6.00. The tag said $12.00, but it scanned as $6.00. The only catch was that they were not refundable.
Their website also says those ugg boots are $6.00, so the price is legit.
If you just want cheap ugg boots, this is a good deal.
You know they can't legally say non-refundable.
If there is a fault with the item you purchase(that you did not know about at the time of purchase) regardless of if it's on clearance or not, you are legally entitled to a refund or and exchange.
