   "note": "We computed the median over a fixed panel: the programs carrying a valid non-prepaid price in every weekly check. Four of the twelve were on prepaid rates: Ivim Health on a 6-month supply, Lemonaid Health on a 3-month drug plan, Ro on an annual-prepay membership, and Sesame Care on a 12-month plan in the August 31 check. GLP Chart has since moved each of them onto the rate a reader can start on today. Corrected, the August median is $348 and not $307, and it did not move against July: the release reported a 1.32% rise that did not happen. Ivim Health leaves the panel outright, because it publishes no month-to-month route at all, so the panel is 11 programs. Three rows also leave the moves list, Ivim Health 200 to 175, Costco / Success by Sesame 408 to 358, Sesame Care 398 to 358, and one leaves the prior-month movers, Sesame Care 358 to 398. Each was GLP Chart restating a basis rather than a program changing a price, and each is itemized in the price history. Costco/Sesame is restated flat to $398 across August rather than carrying a move: it buys the same Success by Sesame plan and the same $299 Wegovy pill as Sesame Care, whose corrected series is $398 in every week of the month, so its earlier $408 was our own stale basis and not a rate Sesame withdrew. It is not in the median panel, so restating it does not touch the figures above. GoodRx for Weight Loss 388 to 338 is a real move and stands. The method did not change and stays at version 1.0. The other three metrics are unaffected: the compounded floor $178, the branded floor $299 and the $121 gap.",
