Resorts and liveaboards that offer discounts to repeat guests

[CWK]

I’m looking for resorts and liveaboards that offer discounts to repeat customers. I’m aware of:
Spoilsport - 5%
Emperor liveaboards - 5%
Master/Siren - 5%
Carpe Diem (Maldives) - 5%
Scuba Junkie - various discounts

What other liveaboards and resorts offer discounts to repeat guests?

Coco View, Roatan. 1 free land pkg after 9 visits.

Essentially a 10% discount.

Many hundreds given out due to high repeat guest rate.
