dieselgiant.com is way overcharging! $20.50 for two cans!! (albeit includes shipping but still).

They have it for $5.95 a can (amazing), but i go to checkout - shipping is $14.50 to NJ!!! regardless of whether I have 1,2 or 4 cans.
Any other sites that sell this where shipping might not be so much.
Or even better a store in NJ/nyc area that might have it - I got two bottles of seafoam at the local autozone but i'm going to return them because i decided i really do want the lubro moly stuff. The can looks cooler too
