To understand the answer to this question, you will first need to comprehend the reason why Goodwill offers the Color Tag day. The color tags on their merchandise determine which items are old enough to be sold off quickly. For instance, the blue-tagged items are regular products available at 30% off on Thursdays and Fridays, and the black tags are usually high-end clothing items that are available at a considerably lower price than the original rate.
As for the Green Tag, it falls somewhere in the middle. The Goodwill senior discount days that offer the green tag lie in the middle of the month, the second week to be more precise. Green tagged items are generally offered at a 30% discount on Thursday and Friday, and at a 50% discount over the weekend.
