These can't be bought at 1.33 and last suggestion shouldn't have passed. There was no proof of 1.33.

Here is my trade. Its been the 3rd day and I still haven't bought it for 1.33

Last suggestion many people disagreed on the 1.33 in the range. See here

There are just 3 pages and many people are highballing while some sell for reasonable prices. But 1.33 is not found and can't be really bought with 1.33

My offer of 1.66 gets rejected here

On steam Market it is sold for 1.38 average, converted 2.49 ref

That is it. Cheapest one found was 1.66 which is already sold. Others are selling 2 ref or above
