I check it every morning. It is a link site - they don't sell anything, just tell you who has the best deals. I work next to a Cabela's and use the free ship to store quite often.
Have to be quick though, cheap stuff goes fast. Yesterday the deal was 500 22 lr for $ 24.99..
Today has 300 22 lr with a silly wood box for $ 24.99.
