Work Inteferes with My Shopping Schedule

I was there yesterday and tried on the boots, but I didn't have the right socks, so I couldn't really tell how they fit. Instead of doing the smart thing of buying them with plans to return them if they didn't fit right, I left them there (sob!).
Now I must atone for my abandonment of perfectly wonderful boots and drive back there today to rescue them (and to return a wrap/shawl thing that didn't really do it for me once I got it home). Unfortunately, I have to work (work!) today from 9am to 3pm.
