All full systems & Tailor Made (part system) sales @ £60
Neatheat (MP3 part system) sales and Upgrades £500 @ £40

Net Volumes in excess of an HSAs monthly Volume Threshold will be paid in
proportion to the split between Full & Tailor Made part systems and Neatheat
(MP3) part systems sold.

e.g. If the total sales in a period were 85% Full & Tailor Made and 15%
Neatheat (MP3) then all sales in excess of the Volume Threshold will be paid
at 85% x £60 and 15% x £40
