I have to agree with others who have said the vouchers, while a super kind gesture, weren't what kept us coming back. I'm pretty sure we all love this brand for the awesome products. The great people and amazing customer service just send it over the top and make it that much easier to love. Speaking just for myself I'm going to buy the stuff I like regardless of if I am going to be recognized for it. Expecting a reward feels counterintuitive to me and seems to be expected by people too often these days. I think its incredibly admirable that you would offer to replace this with something else, but just continuing to do what you all do and make these fine products is what we really want!
I'm sure you all will still find something that feels right to fill the space, but don't let anyone say you aren't doing enough!
