Just for today, Groupon offers a $20 Credit at EverydaySource for $10. The same deal was offered by Groupon Minneapolis yesterday, but it sold out before the day was done. That matches the best such offer we've seen for this merchant, which specializes in electronics accessories. Most items qualify for free shipping. This credit can't be combined with other offers and must be used in one visit. Although this is listed under Groupon Detroit, it can be purchased and used by anyone.
