Quote from @Shiv Panda: You can buy them online, maybe even at large box stores like Home Depot, Lowes, or other appliance retailers.I did a search for "commercial washer dryer card operated" and came up with many sites that sell them.

So sometimes I have clients who recorded a deed on their own (they got a template from an office supply store and sent to the county to record), but that can be a problem since the title companies are very wary of fraud. 

Okay, I'll jump in here.I've done SBA 7(a) loans, one for 1.7mil and another for 2 mil, for two separate commercial properties (gas station c-stores, ground up raze and rebuilds). 

Go to a local convenience store, see what kind of people live there. 

You can buy 2 prong outlets at most any hardware store, home improvement store, electrical supply store. 

When people open the doors, they are envisioning how to store their cookware, etc.

Important Documents Lastly, make an electronic copy of your closing documents and store the copy you receive from closing in a safe place.

You could build a flex-space building for the plumbing company to relocate their office and warehouse AND have enough parking and now you get 5-10K a month or more in rent. 

If you're looking for somewhere fairly safe and consistent to store cash, land purchases in this area could be a good option.

I would contact the store or manufacturer and see if it falls under warranty.
