Validity of the quotation

I am going to purchase an ofuro in 6 months from now. Will the quotation still be valid?
Please note that the quotation is valid 1 month.
Unless there are major market changes, our prices do not vary, although shipping charges may fluctuate according to oil and local currency exchange rate variations.
Let me know when you are ready to finalize the order and I will provide an updated invoice at that time.
