I pretty much do a quick look to see what I have as well. With just one Vino, it's easy to open the drawers and take a peek.
HOWEVER - I do keep a strict log of my purchases... I bought a book of 'receipts' at the local CVS and fill them out myself with
the date of purchase, from who, where, what, and how much. I then break it down by dividing the total price by the number of sticks
to get my 'price per stick'. This way there is no confusion when I go to do a sell (which has yet to happen, but at least I am prepared
to offer a 'fair' price based on my notes.) I then tape the individual receipts to my "Cigar" notebook where I also write to the side of
the receipt, a little information on the cigars I purchased. Just helps me keep track more on how much/what Im spending my $ on.
Here is a brief pic of my notebook. . .
