Personal retail is what your customers buy from your catalogues.
Just 1 thing
Circulate* say 200 catalogues per week until you locate** about 200 customers and then you will earn €500 / £350 a month for around 10 hours effort a week.
*Circulate - Leave catalogue with a potential customer for 2 days collect back and deliver any products ordered.
**Locate - By putting catalogues out in a particular area and keeping note of who bought. Once you have been round an area 2-3 times you will have your list of customers. Once established just go round your chosen areas every 6 weeks or so circulating catalogues to your existing customers only.
