We just bought a My First Jump N Play bounce house from Sam's Club. It was marked down to $149, and when we went to check out, it rang up at $119.81. The original price on it is $179.98.
for reference, because it is marked down in-store only.
For what it's worth, they had other summer toy deals marked down at both of our stores, as well. There was a squirt gun shield two-player set that came up at $4.81, but hadn't been changed on the sign until today. Another deal was a sling shot with rapid-fill water balloons, marked down to $9.81. I didn't find either of those online, though.
As always, YMMV, but the seasonal aisles are definitely worth checking if you're going to be out and about. I attached a copy of the receipt, for reference.
