Deductions & credits

Sorry, you wrote: why don't you take the sales tax deduction?  

I'm not taking the sales tax deduction because I don't know what that means.  This is getting too complicated.  I know you can do it through a simplified method, without saving receipts, but my medical expenses were high enough on Schedule A.

Are you saying that since I am not taking the Standard Deduction, I could deduct the Sales Tax paid and should?
