I do the opposite. I buy a bag of green ones, and put them in the fridge. They stay green for a while in there but do start to slowly ripen. Before I put them in the fridge on day 0, I put one on the counter, and one in a brown bag. The brown bag is for day 2, the one on the counter is for day 3 (there is no day 1 after day 0, at first). On day 2, when I take the ripe one out of the bag, I take another out of the fridge and put it on the counter for day 4, and continue this process. When I take the last one out of the fridge, I have another bag ready to go in. With the right timing, this provides a perfectly ripe avocado per day.
And for storing a cut avocado, the press & seal plastic wrap works wonders. The trick is to not let air touch the exposed bit. If it does, then just slicing a thin slice off the top exposes the green part again. (This also works for frozen loaves of bread that have been cut - just a thin slice off the end gets rid of the bit that was destroyed by ice.)
My memoirs will include all my food storage tips for the perpetually single.
