Today only, until 11 pm ET, eBay takes $15 off select orders of $75 or more via coupon code "CSAVE15OFFMARCH" during its Flash Sale. (You must pay via PayPal to apply the discount.) Plus, most qualifying orders receive free shipping. That beats our mention from a month ago (which only took $10 off orders of $50 or more) and is a rare general discount from eBay. It's also one of the best dollar-off coupons we've seen for purchases in this price range.
Note that this coupon can only be used once per account.
