This covers roughly the last 6-7 months. Everything can be verified by performing proper searches throughout /r/DNM and /r/thebarbarians
Last summer, there were Relaxing, DrXanax, Quantik, MsBliss and Bobafett selling/involved in the bulk xanax game.
April 2015: Quantik had the game on lock down before this time, but loses his alp powder plug. The "DrXanax" vendor account is created.
July 2015: Q found a new plug, but DrXanax sabotaged Quantik and took control of the game for the 2 next months. Quantik has bunk, crumbly bars and has to reship virtually all the time. Thebarbarians sub is created around that time by /u/EastCoastBarbarian
September 2015: Bobafet & Galactica doxx DrXanax to Q after DrXanax stopped buying powder from them. Q takes down his operation, claims DrXanax has infiltrated his OP and a short shillling war between Q and DrXanax follows and /r/thebarbarians goes private (in part) because of this.
October 2015: DrXanax & team gets busted HARD and it turns out they were a bunch of kids with zero opsec who used to work for Q at some point in the past and decided to break loose with stolen equipement.
Quantik and Bobafet start to take-over the market, with Bobafet being the only plug at the moment for R039 bars.
November 2015: Bobafet ships a shitload of PX1 bars & pocket sand and exit scams, singlehandedly destroying the R039 game for months.
MsBliss, Relaxing and many other vendors quit or scam because they can't handle the volume of customers caused by Boba's exit. Q is pretty much the last bulk retailer standing at this moment and decides to raise prices due to "Supply and Demand".
December 2015: Quantik takes control of the game by hiring several USA domestic resellers, with the biggest being "QuantikUSA", formerly Candyland134.
Bobafet merges with Relaxing and rebrand as "Barbarossa".
Quantik goes balling posting pics of his labs, stash and stacks of cash & drug usage in /r/thebarbarians.
January 2016: XanaxBaron joins the game & offers $20 samples that turn out to be 300+ pills. Tons of reviews pop up. FUD is through the roof.
Barbarossa undercut Quantik & resellers prices by 10-20% & allegedly tries to get XanRuS, a Q reseller, busted by ordering bars from him, shipped to a cop station.
Less than a month after opening, XanaxBaron closes shop due to possible package profiling because some packs remain stuck at acceptance in some Canadaposts. His opsec is highly criticized by the community.
QuantikUSA, the largest Q distributor, gets busted and it turns out they were all hillbillies from a tiny town in LaPlace. Quantik & resellers' anus peckers due to the heat. Quantik closes shop.
Some 20-years old french canadian gets busted attempting to cross the Quebec-vermont border with a sled filled with 200 pounds of xanax pills in white camouflage suit. He is held without bail in vermont and doesn't speak a word of english. Many speculate to possible ties to Q and/or DrX.
/r/thebarons , an open subreddit for xanax resellers, opens, created by /u/FirstBaron
February 2016: By now, most Canadian vendors have closed their shop.
XanaxBaron re-opens shops, claim "Profilage" was a false alarm. All listings are open but XanaxBaron won't ship them till next week.
OlympusXans stops reselling for Barbarossa. (Probably for the reasons below)
Right now: based on reviews & complains, Barbarossa ships pocket sand / bunk bars 1 out of 3 batches and his subreddit is a more censored place than North Korea. But he's an option for domestic bulk considering there's no where else to go.
Sums it up.
No, this sums it up.
