Perfect Topping was the first item I bought full price at the MAC counter when I was first getting into MAC
Not counting the Select Cover Up that I bought 6-8 yrs ago, before I was really into m/u.
On the subject of why they send hot items to CCO's - my friend (a NARS artist) told me that sometimes whole batches fail because they're slightly under the weight range or minor labelling issues etc. I think this is why we see things at CCO's and warehouse sales when they actually sold out at counters. For example, the free door gift at a recent MAC/ Estee Lauder warehouse sale in Toronto was Perfect Topping. That's thousands and thousands given away for free. At the last sale Triple Fusion and Smooth Merge MSF's were in the charity bags, and I noticed that mine had a suspiciously flattened dome, as if it had been used. I bet it was rejected by quality control.
