Current Half Price Offer

[#1]

If a new customer signs up to the 'Value' product and then re-grades within the first 12 months to the 'Extra' product will they be charges half price for that too for the remainder of the 12 months?
Also, will referrers receive the standard referral value for the account even though they are half price?

[#2]

Which ever product is chosen on signup will be the discount applied for the duration, so if you went from Value to Extra then you would receive the Value discount.
Referrers will get discount according to the current product the referrals are currently on, it doesn't matter about any previous package or offer.
