Link To Deal Link To brickseek

This is def a buy already since ~$14 for 6x for Tote Box Plastic Box 30 gal is steal price already. Usually, you could only get 1x this price. (See image at the bottom)

Also check BrickSeek to see if there are any discount at your local store. If price is lower on brickseek, do pickup order otherwise, simply do shipping.
