Version 2.3.3

Fixed discount logic.

Fixed PayPal order totals not matching

Fixed add discount code from product page exception.

v2.3.2

Added backend form to add / edit / delete accepted promo codes.

Important note

Once you add new codes here, they will only work for products if the product’s google_promo_code attribute option text matches the code saved in this table.

So the flow is now:

add code in admin grid, e.g. SPRING10
set product google_promo_code option to SPRING10
assign a matching Magento sales rule coupon SPRING10
your extension will allow and process it

V2.3.1

Added on and off switch for the module in Configuration / Sales / Merlin Multi Coupon, this enables / disables the product page buttons and stacked discounts logic for the cart and checkout.

Code changes to pull accepted deal codes from the database rather than hardcoded.

Next version will bring the backend options to add / edit / remove acceptable stacked codes.

v2.3.0

Lots of issues have been fixed in this version, with better code handling for Make An Offer Extension to run alongside existing deal codes and logic to make sure no double discounts on any product.

Version 1.0.1

Added: Allow only discount codes which are applicable.
Fixed: calculations including vat.
Fixed: Clear Codes and Remove Code buttons
