Actually I am not even sure this sale is really all that early since you actually have to buy your Mom a gift before Mother’s Day. Google knows that, so they are already offering 1 year magazine subscriptions for Mom at $5.00 off plus select books at 50% off. The sale will run through May 5th, but I would hit the source link now to get your orders in before you forget. You might want to pick up a Nexus 7 for her as well, but unfortunately they aren’t on sale.
Mother’s Day is May 11, so make a note of it.
