Shipping cost estimate and quantity breaks

[Raj Saini]

Hi,

I am configuring shipping cost estimates for my website with the help of 
DemoShipping.xml. In the demo data I found all the quantity breaks are 
same except quantityBreakId. Do we need separate quantity break for each 
ShipmentCostEstimate entry? Also in demo data I see fromQuantity and 
thruQuantity as 0.0. Does it mean that it will match any weight for the 
shipment?

Thanks,

Raj
