We would not want two prices where one price falls inside another effective date range except in the case of a blank end date - ie no end date - the default price for the currency/salestype.
I first thought that we would need to update the previous default price (blank end date), when a new default price is entered, to have an end date of the startdate of this new default price less 1 day - but this is converting a default price into a special price which could result in having two special prices over the same date range - best to leave it unchanged and use logic in the GetPrice.inc to ensure the correct default price is returned
*
* After further discussion (Ricard) if the new price has a blank end date - i.e. no end then the pre-existing price with no end date should be changed to have an end date just prior to the new default (no end date) price commencing
