Many Goodwill stores across the United States implement a "Color of the Week" sale, a program that allows shoppers to receive 50% off items marked with a specific colored tag, sticker, or plastic barb. This color system, typically cycling through five colors—purple, green, orange, blue, and yellow—is determined weekly by each individual store.

The "Color of the Week" sale is not a uniform national policy, and participation varies by location. Each store decides which color will be discounted each week, typically from Monday through Sunday. Once all five colors have been featured, the cycle restarts. For instance, during an "orange week," all items bearing an orange tag or barb are 50% off for all shoppers, requiring no membership or coupons. These discounts are generally applicable only in-store, not for online purchases.

Some Goodwill locations may also offer additional discounts. For example, certain stores might extend deeper price reductions during the last week of each month. The Goodwill of Middle Georgia and the Central Savannah River Area, for instance, offers 50% off housewares, books, and accessories weekly. On the fourth week of the month, clothing items with the designated tag are priced at $1.25 on Mondays, and housewares, books, and accessories are $1.99 on Wednesdays.

In Arizona, some Goodwill stores display a sign at the entrance indicating the week's 50% off color. Additionally, some stores in that state offer items for just $2 on Thursdays. For seniors aged 55 and older, some locations provide an additional 25% off their total purchase on Tuesdays, requiring a valid ID at checkout.

It is advisable for shoppers to contact their local Goodwill store directly to confirm if it participates in the "Color of the Week" sale and to inquire about the specific discounts and participating item categories. While the color tag sales often apply to clothing, housewares, and accessories, they may not extend to newer items, electronics, furniture, or specially priced merchandise.
