I must be the only guy on FT who uses Paula's Choice (cleansers, toners, moisturizer and the very good shave gel). Long-time user but the prices have been inching up over the years. I buy in bulk during the times in the year they have free shipping e.g. Memorial Day, the recent Labor Day etc.
But to keep it on topic, I re-use the empty toner bottles (2oz sizes) to bring along travel-sized shampoo/conditioner etc (alas, I do not use Paula's haircare products) - it's small enough and I'm sure it won't run out - sometimes I am on the road 9-10 days at a stretch espcially if I'm in Europe or Aisa.
