i've seen this several times now:

the combo price being higher than the sum of it's parts !?

KMP Spit $489.00; KMP Retracts $199.95 >>> COMBO price $689.00

that makes the retracts 5 cents more expensive in the Combo... aren't we suppose to SAVE $ in combos?

I've also seen seen some combos on Tower Hobbies more expensive than the sum of it's parts[>:]

Isn't there something wrong with this trend?
