Diet pill alli (low-dose Xenical) will go on sale in grocery stores and pharmacies around America on Friday June 15th, according to an announcement on GlaxoSmithKline's official alli website.

The terse announcement said "beginning June 15th, alli will be available in all major drug, grocery, and discount/warehouse stores in the weight loss product aisle."

A number of online retailers have been allowing dieters eagerly awaiting the first FDA approved over-the-counter weight-loss drug to "preorder" alli for shipment the day it is officially placed on sale.

A number of readers have been searching for the lowest price for the diet pill, and have reported their results to our sister newsletter, alli Report.

As of the moment, the lowest price still seems to be offered by MyFloridaPharmacy.com, which is offering the alli weight loss aid starter pack with 90 pills for $58.99.

Two other options also are being offered: the alli weight loss aid starter pack with 60 pills for $48.29, the alli refill with 120 pills for $73.29.

With the launch of sales of the non-prescription drug only a week off, observers expect a new flurry of promotional activity in the days immediately ahead.
