Does anyone know if its possible to get 15% discount with shareholders membership, plus an additional 10% sponsorship discount (presume not!).
If not, can you still be sponsored, forego the 10% discount, but still give the sponsor a "credit" towards his 12 month extension?
Combining two discounts is not possible.
Giving discount but not getting a stamp on your form IS possible (when a minor wants to sponsor someone without his/her parent present, because apparently the parent has to sign the parrainage-form).
I doubt if the opposite, as you ask, is possible. I guess the best way to find out is to ask at the BPA or email DLP.
