The just sell the machines, or lease them. A lot of smaller operators buy in bulk from Costco and use that to stock the machine.
A local supplier would probably be better. But… free shipping! https://m.aliexpress.com/item/1005003798489127.html
Hey thanks! It never occurred to me that it’s something googleable and it would be right there. I would question AliExpress quality but hey this is a great start.
Most cost-effective way would be to browse for an old used one on ebay, should be like $500-1k if you’re in the US.
Like the other poster said, fill it with products from Costco, the only issue is packaging things like single use detergent. You’d probably want a box or something for pods or powder so they don’t get damaged.

Looks like they’re a bit over $1 each, so sell them for $1.50 or $2 in the machine. Don’t confuse them with the sink packets which aren’t for machines.
