Sorry your order got messed up Scot. Several members ordered more than one set. I bet someone will help you out!
I’ve had a couple of situations, and have heard a couple of stories that have led me to the following conclusion. When performing an operation or transaction on a web page, if you get an error, and then proceed forward with the operation, things can sometimes go wonky. I bet you know this, but there’s a computer term called “session”, that Wikipedia defines as, ”A semi-permanent interactive information interchange, also known as a dialogue, a conversation or a meeting, between two or more communicating devices, or between a computer and user.” For a few reasons, I believe that when attempting to perform an operation, if an error occurs, and then you proceed with the action, within the same session as the error (as opposed to closing and then reopening your browser, to create a new session that does not contain the error), things can go haywire.
Maybe it was a coincidence, but I don’t think so. On Greg’s website, the forum indexing became screwed up when I created a new thread and had a similar problem with an error. I tried to launch a new thread, and I used pair of programing symbols within the title of the thread, and I got an error statement. I did not close my browser to create a new session, and I removed the symbols from the post, and proceeded with the operation of creating the thread. The indexing problem was noticed right after that. I believe my first attempt at the process of creating the thread (associated with the error) created software coding that in some way interfered with the second attempt to launch the operation, which I think is why the indexing was thrown off kilter.
I wonder if the Topps / Paypal system interface was confused by the error and that led to processing only part of your cart. Since this has happened to you and other people before, with Topps, it sounds like there is sometimes a communication glitch between Topps and the Paypal site. I think the safest thing to do if one gets an error statement is to close the browser and restart the ordering process fresh, with a new session.
