Whilst your pics are not very sharp, it only appears to me as if you may have a little thinning going on at the front there..your actual hairline has not receded, therefore, you certainly should not shave off your hair at the moment---it`s too soon. I don`t doubt that you`ve become ` conscious` of an issue there, but in relative terms, it`s still small. If I were you, by all means go and collect your system and pay for it, put it into a sealable polythene bag and keep it in a drawer. It will ` hold` / last quite fine, and you can use it at a later stage. In the meanwhile, a little concealer sprinkled in / on will keep you going for now.
That`s just my honest opinion based on what I can see....obviously it`s your choice ultimately.
