Office Depot takes up to 40% off a selection of office chairs. Even better, coupon code "A54725ZGV1W000" cuts $10 off orders of $50 or more. Alternatively, take $25 off orders of $125 or more via code "D907E036K23WXT". Plus, all orders receive free shipping. That's the best discount we've seen on office chairs from Office Depot since last summer, when we saw up to 40% off with an extra 25% off. (For further comparison, we saw up to $100 off with an extra $10 off $50 or more in January.) A couple of best bets, with prices after applicable coupon:
