Dear :

We have received your notification of price increase dated .

Although we can understand the reasons you offered, we dispute the justification for increasing your prices on [date]. Under normal conditions, at least one to two months' lead times should be given to customers. Since your inventory currently on-hand or in transit was purchased under the old pricing terms of you vendor, it is unjustifiable for you to implement an immediate price increase.

We request that you reconsider the implementation date for your price increase as stated in your notification and inform us of your position by the end of this week.

Sincerely yours,

[name]
