Frequently Asked Questions

Can I combine a M&M's coupon code with a StackWell reward?

It depends on the current M&M's terms. These offers are supplied through affiliate feeds, but a code can still be excluded from reward eligibility. Open the tracked offer first and confirm the destination terms before completing the action.

How do I earn the 6.0% cash back listed for M&M's?

Sign in to your StackWell account, open the tracked offer on this page, and shop in the same session. That qualifying event must be reported and confirmed by the merchant network before it qualifies for payout.

How often are M&M's deals updated?

Every day. StackWell refreshes deal and coupon data from affiliate networks nightly, and expired offers are removed automatically.
