Thanks.
Now THAT was an odd checkout. First it kept losing my contents so I'd have to start from scratch. This happened twice. FINALLY I got everything in my card and check out. Of course, I never stop to check the total until just when I hit "Purchase" and I see it's way more than I thought.
What happened is that it somehow kept track of every shopping cart I lost and in the end, totalled it all up. So now, instead of the limit of 9 of each item, I have 18 bottles of ibuprofen, 18 rolls of tape, etc. I guess I won't try to fix it, as we'll use it eventually, but it sure was strange.
