How does $20 worth of toys for $10 sound? Paired with a sale between now and Christmas (you know there will be several!), this sounds like a great deal to me!
And if you don’t need toys? The Groupon certificate is accepted at Babies “R” Us, too. Limit 1 per person and good in-store only, the $20 value is good through 12/24. Should be a great way to snag an inexpensive gift!
