Reitmans has a fantastic sale on this Long sleeve V-neck tee in the colour bud (kinda a deep pinkish red). It is available in sizes 2x and 3x. Originally $20, it is on sale for 50% off ($9.99), and then 70% off that... so for only $3!
There seems to be a whole bunch in stock. I tried adding 10 of each size (2x and 3x) to my cart and all was fine with that.. so a good quantity. Unfortunately, all the other colours shown there are sold out.
