at least with the oils you knew you were done in so many weeks AND had the option to buy them (for a crap ton i know but still). Umbrite you have one option period. Even with dailies your casually getting 2 to 3 a day at best. My point being that if they can do that with the oil....they could add in another place/way to get umbrite. It just feels weird they give you like 10 different ways to get the sands and then added one for umbrite, went to lunch and forgot to do more.
