I know I posted this a looong time ago, but I wanted to update how this problem was solved in case anyone else ever has this problem...and apparently they do, b/c I finally called Wags, and they knew exactly what I was talking about
If you go to 'claim rebates' and your page looks like it's in large print and there is no 'start/add receipts' button, go to the top of your browser where the 'file, edit, view, etc.' buttons are. Click on 'view' ,scroll down to 'text size' and then click on 'medium'.
Works like a charm
