It's our effort to encourage recycling of the refillable glass bottles we use for the Dark Matter cold brew concentrate. Recycling helps us keep costs down, reduces the landfill load and ensures we always have a ready supply of bottles. We ask that you bring the clean, empty bottles to the farmers market so we can sanitize and sterilize them to be refilled with a fresh batch of Dark Matter cold brew. Refillable bottles are exempt from the CRV fee. In exchange we may offer a discount to you on your next purchase of a bottle of Dark Matter cold brew concentrate but we are not required to. The discount cannot be used toward the purchase of any other products. The maximum discount you will receive is two dollars no matter how many bottles you bring back. That's it no more. No, you can't save up bottles and get a free one. This is not a CRV fee which is applied to bottles that are not refillable nor is it any kind of bottle deposit.
