xyz $2.4 (Coupon:RATXYZ)
ME $4.99(Coupon:RATME)
CRICKET $2(Coupon:RATCRICKET)
CLUB $4.5(Coupon:RATCLUB)

Can you please elaborate?
Does xyz costs $2.4, ME costs $4.99, etc... ? Or is it $2.4 discount on the original xyz cost, $4.99 discount on the original ME price, etc...?

I'm planning to add this on my coupon website.
