I've already quoted you the rock-bottom price.This price is quite reasonable.This price is quite low.This is a good bargain/buy!I can give you a 10% discount.In that case,we can knock off 1O%.There is no discount.It's not expensive at all.It's worth the price.Less expensive, lower quality.Cheap things always have bad quality.We don't bargain.It's fixed price.Normally we have no second price.You'll find nothing less expensive than this.There isn't anything cheaper than this.If you buy two sets, I can give you a discount.The price will be cheaper if you buy more.It can't be any cheaper.It's the cheapest.It's cheap enough.Let's meet each other halfway.
