We sell catalogs/magazines and they have a set amount of pages and each has it's own price.

For ex:
qty ordered
1000units 5000units 20000units
12 pages $1285 $3395 $8220
20 pages $2745 $4465 $10690
32 pages $4170 $6760 $14425

I need to set these fixed unit amounts and prices. You cannot order in between amount such as 4900units. How do I do this?

Any help would be greatly appreciated.
