EBMM JPM price increase
The increase will only effect orders placed after 7/21 Summer Namm. But I had forseen this situation and there is a disclaimer at the bottom of the JPM page covering just this scenario,
IbanezRules cannot be held responsible for errors in EBMM's own figures or in any future changes they make in the pricing schedule, they have already 'adjusted' prices once already. If the prices from EBMM change after you order you will be responsible for any additional amount, or be entitled to a rebate, the sword cuts both ways :-)
This does not apply in your case. If it had, you would have to pay the higher rate though, I (nor any dealer) cannot be held responsible for manufacturers pricing fluctuations.
