Price gets better if you buy the 3 gallon, $44.00. Just a heads up https://www.amazon.com/dp/B01LH7L0KS/ref=twister_B073R5TFBL?_encoding=UTF8&psc=1
So reading the fine print on the rebate form leads me to believe that you can only do one bottle per form, and a max of 4 forms per household. So you'd just have to fill out 4 total forms if you purchase 4 gallons. Too bad the 5 gallon buckets aren't comparitively priced... $35 a bucket rebate.
The rebates can be filled out electronically on shell's website. If you could find a local distributor I would venture to bet the 5gal bucket price would get alot better. Shipping a 5gal bucket is expensive.
