Again I'll ask - if we wish to change our delivery option, can it be subsidised to the value of the "free" shipping option?
For example:
DX Secure would cost £5.50 to deliver without the free delivery option. OcUK offer this as the "free delivery".
DPD would cost £8.30 without the free delivery option.
If I choose to change to DPD, could the additional cost now be £2.80 - the difference between the two.
OcUK would not be "losing out" on money by offering this, as they would be charging £5.50 for DX Secure delivery without my loyalty discount, and I am more than willing to pay the difference between delivery options.
