Congrats on still being here.I am still in both leap year and decade restraint, no temptation at all.
I am not sure it is a good idea to have a reward for those surviving the restraints. The main reason I joined is that buying soaps somehow got out of hand and I ended up with way too many soaps. These restraints are for me the best way to stop hunting for the next best soap and concentrate first on using all the soaps I am already hoarding.
The idea to get rewarded with a soap for not having bought additional soaps during the restraint is not really what I am looking for, especially as at the current pace I might well still have quite a few unopened soaps around by the end of the decade.
