I'm so so jealous of you just being able to go to Walmart on a whim!! I LOVE WM, as does my DH, and going there was such a thrill on our holiday in Maine last summer. DH and I went to NYC last week (our first time going anywhere alone together since DS was born 7 years ago) and I was researching the closest WM but it was too far away.
Lucky you with your embroidery machine. You were in the right place at the right time (and with the right man!!). Enjoy your new purchase. It'll be all the more enjoyable for being a bargain.
