OK, no card (as many others have stated). If you should happen to see someone using a card it's because they are using their Publix U Promise card, free to join and it offers savings for college thru the U promise program. It offers no savings to the items that you are buying, just $$ for college. You can ask any cashier for it at the checkout and they can give it to you and you can use it that day.. the only catch is #1 you can only use the card at Publix and #2 you must activate it online or over the phone before you use it again or you will loose the "points" assessed the 1st day.
Most all the items at Publix are top notch, way above the competition is quality. People will sometimes say that the prices are higher, well that may be the case in some circumstances but.... #1 quality is superior, #2 variety is unmatched, #3 honestly, I can't see THAT much of a price difference... sure maybe a penny here and there but it isn't enough to make me shop elsewhere. (and I'm a super shopper)

The customer service is AWESOME.. they offer complementary carry out service and TIPPING is not accepted. This is a service they offer for free and you do not have to tip for it, the workers can get in trouble if they are caught taking a tip.
So many items are just sooo good, the Bakery yummo! Fresh everything! The Deli is delish! Produce is always fresh and inviting!!!
Also, while it is true that they do not double coupons, no one here in Orlando does, they do accept a Publix coupon and a manufactures coupon for the same item, if you have it! look at the front of the store, there will a large stand (it turns) and they often have Publix coupons available there! Also, the sale prices can't be beat.. for instance, I got Lysol, large size on sale of $3.99, I had a coupon for $2.00 off so I got it for $1.99


! Look online for their sales flyer...... it will help in planning your shopping trip! Also, they have this thing called a Publix Promise... If you purchase an item that rings up more than what is priced on the shelf, you get one of that item free! (no alcohol or tobacco tho..) The pricing is usually pretty accurate, but look out for it, you never know!
