Found several of them at at least 2 BJs for 16.98. Online most places charge $100+ for the same.
Great product if you have kids 2 to 8 who cannot make the beach trip this year. Just make sure to use bungee cords to secure the lid when not in use.

Some reviews mention rainwater going in, but the one I have has been completely dry after at least 5 rainfalls to date.
Also, a tip I found online: Add cinnamon power to the sand to keep out insects.
BTW this is a really large size and unlikely to fit the trunk of most smaller cars. You will need to fold down rear seats or tie it to the top of the car to transport it.
