Is it possible to price by quantity blocks?

[Lance Monotone]

I've got a shop that is selling stationary. Our individual products are priced per quantity ordered, and are only available in these quantities (which are different for each product). Does anyone know if this can be done?

For example:

25-$188
50-$217
75-$259
100-$290
125-$332
150-$382
175-$427
200-$468
225-$508
250-$549
275-$591
300-$633
