Question on ordering from Toys R Us through Amazon

[frannn]

I ordered some videonow stuff from Toys R Us through Amazon on 12/9. The stuff is now showing as out of stock on the website. I added two more things to my order today, and was able to combine all into the old order, since nothing shipped yet. My concern is that the only thing that is showing as ready to ship is the car adaptor. All of the discs are showing a later expected shipping date. What are the odds that I'll get an email saying that the shipment will be delayed, then another email saying that the items are sold out, so I won't ever receive them? Do I further delay my order each time I add things? I don't mind if the items don't get here by Xmas, but I would hate to not got them at all. Anybody else have this issue in the past with a "hot" selling sales item?
