listen up, (ok, READ up

) as i was saying, over the past few months, I haven't seen any of the old land before time movies in stores lately-
here are the stores I checked-
Wal-Mart- It used to have like EVERY LBT movie and combo packs (which I thought was annoying, but that was before my LBT obsession revival (March 2008?), now they don't have ANY, oh wait, they do have the 13th one, (i think) and i don't remember seeing any TV show DVDs there, but i think there are, and in the Toy section, they have a lot of old DVDs that are really cheap (Scooby-Doo DVDs, Nickelodeon DVDs, TMNT DVDS, etc.), they had like 5 copies of Time of the Great Giving, but that's it. what happened?
Target- Same thing as WalMart, and all i see now is the 13th movie (i haven't seen it on any shelves in months, though) and a few TV series DVDs (same thing as the 13th movie). I even went to the Target in Hollywood lat year and all they had was the 13th movie.
Best Buy- Ever since the time months ago i saw copies of the 13th movie, TV Series DVDs and the 15th anniversay edition DVD, i haven't seen ANY LBT movies.
Blockbuster- They always get lots of copies of the TV series DVDs, and they have like 1 copy of most of the moviess
Universal Studios Hollywood- at the Cartooniversal store, there were lots of cartoon DVDs from Universal, but I'm preety sure thre are a few LBT TV series DVDs there.
Toys R Us- one of the most reliable sources for LBT DVDs, they have all the TV series DVDs, plus the 13th movie, and 10 months ago, HALF A SHELF was PACKED with Land Before Time DVDs and a sign said $7.50 all Land Before Time movies. sweet deal. but last time i went i only found TV series DVDs (obviously)
KMart- I HARDLY come here at all, but they do have a LBT combo pack, the 12th and 13th movies and all the TV series DVDs
So... have you noticed this lately?
