Where can I buy aquarium silicone?

Sorry if this is a fish forum cliche, but I figured you guys would know.

Where is the best place to buy clear aquarium silicone? I'd love to save some $ as well if this is something that wal-mart or somewhere else carries cheaper than, say, a live fish store.

Thanks a ton, really appreciate it!

dont buy the stuff for aquariums as its 4 times the price of normal silicone( and is exactly the same). as long as it says 100% clear silicone and dosent contain any anti mould agents your good to go. mine cost £3 in my local paint shop

Home Depot, Lowes, Wal-mart. Just make sure it's 100% silicone.
