Appliances
Costco shopper Melanie Musson shared that if someone buys an appliance from Costco, additionally, Costco will deliver the appliance to your house and, if needed, can take away your old appliance.
“Many people don’t realize they do that, and it’s a big deal because getting rid of old appliances can be frustrating,” Musson described. “They have many appliances available with rebates, including a Whirlpool top-load washer for $579.99 after a $200 rebate.”
Breaded Chicken Breast Fillets
Looking for some delicious chicken breasts from your favorite dining out spot, but want it at home? Head to Costco for huge savings on breaded chicken breast fillets that might not have been on your radar prior.
“I love telling families about Kirkland’s Lightly Breaded Chicken Breast Fillets that are only $13.99 for a big 4-lbs bag,” Cid went on to explain. “These are restaurant-quality in taste, and are perfect for busy families like myself! I just put them in the air fryer and they come out quick and delicious. Serve them on a bun or melt cheese and pasta sauce for a chicken parmesan meal.”
Ecofoil Pans
Musson highlighted that you can get a 30-count of Eco-Foil Half Size Deep Steam Table Pans for only $12.49, something a lot of Costco shoppers might not have on their list.
“These pans are ideal for dropping off a meal for friends, bringing food to a barbecue or potluck, and for when you don’t want to do dishes,” Musson said. “Similar pans cost $3 or more at grocery stores, so the under-50-cents-per-pan price tag seems almost too good to be true.”
