The newspaper boasts these claims for a reason, presumably to increase circulation. What do suppose is the effect of of a dollar amount claim on circulation counts? Would a "$308 in savings!" claim sell significantly more newspapers than "$199 in savings!" ?

My guess is No, but that's just intuition and not science.

And how much money do you think you would have to spend to realize all of these savings? That number (amount spent) usually escapes my spouse's memory when she comes home telling me how much she just saved at the grocery store.
