In most United States Toys R Us stores the TCG items do tend to be marked up quite a bit.
However, if you take the PRINTED* ad to Walmart (or other locally competitive retailers) most will have an ad match policy. This is especially true on black Friday.
*The add must be the printed add you get out of a local newspaper or such as they usually won't honor them otherwise.
The Walmart and Meijer (regional company) stores in my area sell Tins for $15.95 most times. So, I could got to walmart with my printed TRU ad and they be easily willing to match the ad up to any limitations set by the TRU ad.
Also, remember to look for "$X.xx off total order" coupons as these become very common around this time. Again, Walmart will accept competitor coupons like these in most cases to add up some more savings on top.
Hope this can help a little with money savings
On another note, as far as shipping and deliveries go, most retail distributors only get media items (such as video games, dvds, etc..) once every week on a set date. So, if a certain item, like a video game, sold out it would not be unlikely that it wouldn't be in for a good time.
