Gotta wonder about people who enter credit card info into a form without reading any of the fine print, then don't read their statement for months. Sounds like they are not taking their finances too seriously. Between 10% cashback, intelligent use of shipping rebates for Ebay/Petco cat litter/Amazon marketplace purchases and pretty straight forward Price Protection this program is an excellent compliment to using an American Express card(which don't match prices but have excellent purchase protection).
No cashback on returns(duh) and some retailers won't give cashback if you use coupons that aren't listed at Freeshipping.com, though most don't mind.
Even when they don't offer cashback at a store they will usually always give you a shipping rebate, max $10(12 per 12 month period per retailer), even at marketplace sellers, such as those found at Amazon/Newegg/Sears/Rakuten/Walmart etc.
The only real catch is there are 12 month limits on total rebates for Shipping, Portal Cashback, and Price protection; if you hit them you won't know unless you are keeping track. I wouldn't suggest opening separate accounts with the same account address to bypass these limits, as you will forfeit all rebates owed when they close out your multiple accounts. You are probably ok having a separate account for a 2nd home, but it needs the same account address as the billing information on a qualifying transaction.
