What Would I Pay Full Price For

What would I pay full price for:

• Def Leppard Concert (OK any concert, I have never won free tickets to anything, that would be fun tho!)
• Gas
• Stamps
• Doctor Visits
• Prescriptions
• Movie popcorn
• Electricity & other utilities

Ok...  are you getting the idea I don't buy much without a coupon or discount!  It's true.  I'm FRUGAL people!
