We've been selling buckets on ebay for use in WVO storage. I've included a link to the website at the end of this post. These 17 gallon buckets are made with thick-walled polypropylene resin which will hold up well to grease, and can hold hot liquids as well.
Shipping costs are as quoted by USPS. In general, it's more much more economical to order multiple buckets to reduce shipping cost/bucket. We can ship as many as 6 buckets in one package.
