Just thought I'd add that the price would not change on the items priced individually no matter what quantity from each column was selected.

So Full Colour Single Sided - 250 - individual Item 1 would be the same as Full colour black & white reverse - 250 - Individual Item 1

The below will give you a better idea of the problem:

Full Colour Single Sided
250
500
750
1250

Followed by Finishing Options which are:

Perforations - 1, 2, 3, 3, 4, 5, 6, 7, 8, 9, 10

Round Cornering - 1, 2, 3, 4

Folds - Single Fold, x 2 - Roll Fold, x 2 - Z Fold, x 2 - Cross Fold, x 3 - Roll Fold, x 3 - Z Fold

Drilling - 1 x 3mm, 2 x 3mm, 3, 3mm, 4 x 4mm, 1 x 3.5mm, 2, 3.5mm, 3 x 3.5mm, 4 x 3.5mm, 1 x 6mm, 2 x 6mm, 3 x 6mm, 4 x 6mm

Each of these having a singular individual price.
