That deal ends today (Sunday 3/9). It appears about once a month, sometimes with a 'Spend $25' and sometimes with a 'Spend $50'. The store is very coupon friendly, honoring competitor coupons of competitors nearby. Yesterday I was in and sent $52 worth of groceries down the belt so I could get the gas card. Subtotal $102. Now start deducting store, manufacturer and competitor coupons and what I actually paid was $49.17 for 4 totes of groceries and a $50 gas card. Overall expensive store, but certainly the cheapest in the area after coupons!
Their policy is that they will allow one manufacturer coupon and one Publix or competitor coupon per item. On a BOGO that can mean using up to 4 coupons while you are only paying for 1 item of the pair.
