I just discovered today that MWI billed my VISA for $149.95 on 2/19/03. VISA is canceling this charge for me, however when I went into my Quicken electronic checkbook and did a search I discovered that I had missed 3 separate charges yearly going back to 2000 totaling nearly $300.
The only way I picked this up now is that I'm not using this VISA as much anymore and so it stood out when I received this month's statement. In years past it was my primary credit card and the charge just slipped by me.
