We have had it, but I'll often get the free 60 day membership, stock up with a year's supply of cleaning stuff, soap and shampoo, vitamins and allergy pills, then let it lapse until they do another freebie. Sometimes their gas is at quite a discount, but sometimes, like now, theirs isn't falling as quickly as other stations around us.
One big difference, at least for me, is that their meat (pork specifically) isn't "enhanced with up to xx% solution" (aka pumped full of salt water) like most of the grocery store meat. I hate opening a bag of pork tenderloin and watching a bunch of expensive water run out and down the drain.
