Jewelry
If you’re not exactly sure your future fiancée will appreciate your taste in jewelry, you might want to buy the engagement ring at Costco. That’s because it has the most generous return policy when it comes to such important jewelry.
By comparison, JCPenney allows for jewelry to be returned within 60 days from the purchase, conditioned you still have the receipt. Macy’s has a similar return limit of 60 days. When it comes to diamonds, Costco’s only rule is to have it inspected for authenticity, a process that might take up to five business days.
