Large Volume Liquid Soap

[Danlaundry]

What is the largest volume container that liquid soap, in this case Gain, be bought? Looking to keep cost low on my Wash and Fold and would like to buy in largest size available. Is there a 5 gallon bucket, 55 gallon drum?

Thanks for any help

Consider using powder. It's more economical and readily available. Many people buy the 30# bucket of Windfresh at wholesale clubs and get great results from it.

I believe the maximum P&G products come in is 300 oz.
