It looks like the HN bot killed tedroden's comment because it might have looked like a spammy promotion (e.g. we get up to 15% off flower purchases), though clearly it wasn't.

Here's the whole comment:

    Nope, at this point, we don't take any percentage or fee. We even pass along any discounts we receive (we get up to 15% off flower some purchases for example and we pass that along to you).
