It sounds like all MTG products are seeing a decline in ordering by stores. Toss in that once they had the chance, WOTC printed a whole lot more original JS pushing it back down to $75 or so, and I think you'll see a lot of people step back and wait for sales. And WOTC did this to themselves. Hopefully makes for some cheap product. I had fun playing with my wife and son with JS, so I'm likely to get some of this as well if the price is right.
"To play a game of Jumpstart, players simply open two boosters and shuffle them together to form a ready-to-play 40-card deck."
"Jumpstart was primarily sold in 20-card
boosters, with 24 boosters per
booster box.
[10] The contents of each pack fit one of 46
randomly-chosen themes, with each theme having a "rarity" of common, rare or mythic rare. Common and rare themes have multiple variations of their pack contents; in total, there are 121 possible pack contents. All boosters contain at least one
rare, and one in three boosters includes an extra rare. Within each pack, seven or eight of the 20 cards are lands and the rest are spells; one
basic land in each pack (or in the case of the Rainbow theme,
Terramorphic Expanse) features
art that matches the pack's theme."
"The set contained 37 new cards, featuring the
Jumpstart expansion symbol, and almost 600
reprints."
