I had the same issue when I went to collect my prescription Xmas eve. They said there was a supply issue. I spoke to my GP and as I was finding the gel a bit frustrating in regards to drying time, asked for the Lenzetto spray as a substitute. Collected that later in the day to be given 10 containers! So won't be running out of that any time soon. I found the little foil sachets of Sandrena a pain, some wouldn't open and they are just fiddly. The spray is definitely easier to use, but am having to experiment with the dosage to get the balance right.
