I realize this topic is several months old, but I figured I'd chime in to say we had pretty much the same experience with buying the sampler. We're certainly past the rescission period and still intend to use our sampler points anyway, but they very clearly straight up lied to use about several key aspects. The discounts that OP mentioned were one of them, but the bigger one for us is the ability to use sampler points for friends and family. We made it abundantly clear multiple times during the presentation that we were only interested if we could use our points to book for friends and family, because we were unsure of our ability to use the points ourselves in 2 years considering we have our first baby due later this year. The salesperson assured us that we could. I think at one point, he did mention that for the first stay, it had to be us in one of the sampler destinations, but then after that, we could use the remaining points as if we were full club members. Well, at least according to the actual contract, that is not the case at all. The sampler points can only be used by us, and they are limited to the sample destinations.
I'm honestly shocked that I fell for it, as I'm usually pretty careful about signing stuff, but we also did it on a tablet with DocuSign, and the salesperson was quickly running through all the initial lines giving us summaries of each point, so that must be how it went over my head. The sad part is my wife was legitimately very interested in upgrading to the full package in 2 years, but this kind of shady sales tactic doesn't instill confidence in the company going forward. We should still be able to use our points and the amount we paid was quite reasonable, so it's not the end of the world, but I hope others might see this before getting tricked into a sampler package they can't use.
