Before you redeem any referral code, it's worth spending two minutes comparing what's actually on offer. Bonuses vary widely between brands, and the biggest number isn't always the best deal once you account for minimum order values, expiry windows, and eligibility rules.
Start by checking whether the offer applies to new users only, or whether both the referrer and the referred party benefit. Then check the expiry — some codes are valid indefinitely, others expire within days of signup. Finally, read the fine print on minimum spend or account verification requirements before you commit.
A little diligence upfront saves the frustration of a code that fails at checkout.
