What to do if the SolderStick coupon code does not work

Common reasons

• The code may contain a typing error or an extra space.
• The selected item, account or delivery destination may not qualify.
• A current sale price or another promotion may already be attached to the cart.
• SolderStick may have changed or ended the offer after it was checked.

What to try

1. Copy DINH exactly and paste it into the discount-code field.
2. Confirm that the selected item and your destination qualify for the offer.
3. Remove any competing code, reapply DINH and check the order summary before payment.
4. If the code still does not work, email the code, product link and cart subtotal to contact@candidcodes.com. CandidCodes can recheck the offer, but order, payment and delivery issues must be handled directly by SolderStick.

How CandidCodes checks SolderStick offers

CandidCodes separates each product’s current sale price from its crossed-out original price and checks the visible checkout result for the DINH code without extending it beyond eligible orders, and reads prices in the store’s base currency (US dollars ($)). Only items with a genuine crossed-out price are listed as product deals, best-sellers are shown at their current price, and shipping and return details are matched to the store’s published policy pages.
