The way that we calculate the price for our Books and Albums is by base-minimum + any pages over the base-minimum.
MILK Photo Books and Albums are priced by a base-minimum page count rate + extra pages charged at the regular page rate.
The amount showing next to your MILK Photo Book or Album in your basket is the cost for the base-minimum page count and the extra pages amount is the cost of the extra pages on top of the base-minimum.
If you have pre-purchased a voucher with a number of pages at the discounted amount and want to add more pages, you can do so as long as you do not exceed the maximum page count.
Any pages that were not pre-purchased in the deal will be charged at the regular rate at checkout after the voucher is applied.
