I can't speak to this however, West Coast shaving has the real deal. The small bottle is the glass of old with the white button top. So is the 150ml bottle (with the white button top) even though their website shows the atomizer lid. Their price is only $17.00. I ordered several items so the shipping would not cost too much.
Well, whatever you do online, best to avoid that website that walmart fronts. They sell a single 2.25 oz stick of Old Spice deodorant for $14 (reg. price $18 with a $11 shipping) and drugstore.com sells the 3.25 oz version for $4 and whatever shipping is.
