Bulk Pricing or Price Breaks

[techtech]

Afternoon,

 

Using 1.6.0.6.

 

I would like customer that order 50+, 100+, or 250+ to receive bulk price discounts.

 

I have created 3 cart rules and 50+ items purchased gets 10% off, 100+ gets 20% off, and 250+ get 30% off.

 

I have configured them for 2 very similar products that can be added together to create 50+, 100+, or 250+.

 

I have also said that if 100+ is desired, the 50+ and 250+ price rule is not used (no combinations of price rules basically). I have also said if 250+ items is purchased the 50+ and 100+ price rules do not apply. Lastly if 50+ is purchased, 100+ and 250+ do not apply.

 

However when I use the cart and add the items of 100+ or 250+, 50+ discount is only added.

 

Any suggestions are appreciated!

 

For testing I have enabled each on their own only, then some on their own with one other, but no true price rule singularity is achieved.

I have talked to Prestashop and they said to buy someone's plugin. Is this great customer service?
