Sense Sonnet - Pumper

 Game of Tag

A Costco Warehouse price tag, I

Can be a member's helpful friend

If what I tag is a good buy.

Besides price, other tips I send.

Whatever my ending cents be,

One needs to keep a few in mind.

Point 99, full priced is me.

Point 97, one will find

A clearance on my item, so

Buying it now is a great deal.

Other point numbers one should know,

If a good buy and good to feel.

Knowing some secrets of my price

Can tell if I'm naughty or nice.
