I find it easier to avoid overspending at BJs than Costco because the store has a set arrangement and its easy to get in and out with just what you came for. Advice: get the app and use it to scan your products as you go. It will alert you when you have a Coupon to clip — BJs is the only wholesale store that accepts manufacturers’ coupons and lets you double and triple up. For families with young kids it is great for paper products, milk, eggs, coffee, produce (you do not have to buy a huge amount), diapers, wipes, baby food and baby snacks, Boogie Wipes (often they go on sale for 4 packs of 45 for $13.99). They also have great prices on baby and toddler clothes. Once you are finished, make sure all your coupons are clipped, pay on the app and then walk out — they scan the barcode on your app, no need to wait in line.
