In testing some promotions (coupon codes) for CBSubs, when entering an invalid coupon - because the "To which plans this promotion applies" field is set to a plan that is not being purchased, we get the notice that the plan is not applicable; however, the part after the ":" ("Promotion does not apply to this item.") is sometimes duplicated.

Here's one example:

Coupon code YMA-FF-COMBO is not applicable: Promotion does not apply to this item. Promotion does not apply to this item.

Sometimes the phrase "Promotion does not apply..." is shown twice, sometimes once, sometimes three times, etc.

I can't see any obvious correlation to any setting within the promotion or the qty of items subscribed (although there are usually multiple items in the basket when this happens).

Any ideas?
