I've worked at Costco for 8 years. Here are 11 products I swear by getting at the chain.

• Kirkland Signature roasted almonds, shelled pistachios, and nondairy oat beverage are staples.
• I also enjoy stocking up on distilled white vinegar, coffee, and certain medications at Costco.

My FoodSaver has been an incredible kitchen tool.

I keep Kirkland Signature arthritis pain relief gel on hand.
