Funny, How the header of your post pops up after last week. I F..ed-up. Berton & I had a trade with just over 500 cards going both ways. Not only did I miss 12 cards 9 of them were of one set. I missed 9 in a row. ??? Completely unacceptable in my eye. It was panic, then shame.
Yes, I did get them in the mail the day of reading the message.
I always look for the tags on the end and list them on my lists as a&b&c. That way if I did not catch its variation. I would there when I deleted them from my lists.
As for not missing a card again. I'm going to take the time and checkmark them as I go and not just keep rolling the wheel down the list looking up and down from the screen to the box of cards without them checking everyone.
What is that behind you!?! Oh, It's me! Looking at the cards you have, That I want. :)
