All stores around here run their sales Wed am through Tues pm/up to midnight. This is what I have experienced in my shopping at Lowes Foods. Your experiences may be different.
Lowes Foods
They changed their coupon policy- store card, doubles up to face value of .99, 20 max, 2-3 internets per order, accepts other store coupons but questionable about doubling but the location on the corner of Guilford College Rd and Piedmont Pkwy stopped taking the target internet coupons, will accept 2 coupons for bogo items, will do overages if the coupon exceeds the greenpoints sale price, seems to be falling into a pattern of doing triples a week or two after Teeter each time, you can get a definite heads up on hotcouponworld - got about 1 and half weeks notice this past time.
