Through August 2, you can get $10 off your $40 online purchase when you select 'store pickup' at checkout. It's only valid on certain items. It will say under the item which promotion it's eligible for. If you have $40 worth of eligible goods, the $10 should automatically come off at checkout - no coupon code necessary.
If you have any upcoming weddings, you might be able to find something on their registry that qualifies. I did!
