Accepting credit cards at craft shows.

I got a call from Merchant Warehouse accepting credit cards at craft shows. What they suggested was a $119 machine that accepts credit cards wirelessly with just an electricity source. (Which is great for the shows!) So I gave them an application and I have to fax papers back, I'm going to pay for the machine on Tuesday when I get paid, and then I'm good to go! They'll send me the machine within 6 days and I can start accepting credit cards immediately at the next show I'm going to do! (Which is going to be in April, where I'll need one of these machines. The one in March they have everything covered for us!) My mom and I agreed that this is a good investment for our business!! I'm excited.
