Rose,
I know when I buy something I am sure I will find it cheaper somewhere else...and sometimes I do. Large purcahses drive me crazy because I value a buck and I don't want to see something I like better later. Sometimes I do and sometimes I don't. I diagnose you as normal. I know you value a buck and you did your research and then some. Go forth with confidence...you did all you could.
Keep it simple
JT
