3. Other Potential Meanings:

  • “Coupon-Engine Prototype” (GitHub): This is a software development project and not a source of consumer coupons.
  • Video Game “Prototype”: Websites selling game codes, like AllKeyShop, might list price comparisons and potential discounts, but not typically “coupons” in the traditional sense.

To find the most relevant coupons, please specify which type of “Prototype” you are interested in.
