Zapor rescue an old-timer with Ricoh toner cartridge online

I am a pensioner of 73 years old. Exposed to the use of computers for some 30 years, but always scared of the mechanics. Only started to buy online recently - very scared. I do a fair amount of printing, but always looking to save on ink & paper - refilled my own ink for many years till I switched to a Ricoh toner printer some 5 years ago. After all the local "refillers" of toner left Bellville area (Last one filled for R390), I was forced to start looking for the SP100e cartridge online. Zapor advertised for R299 + delivery cost. I was tempted but scared. Two months ago I phoned and the lady confirmed they stock the cartridge. I postponed because I was scared to buy online from unknown people! I noticed that they had one bad report, but a few very good ones - but decided to take the chance - based on despiration! On 15 October I ordered (adding a ream of paper to make it wortwhile) and struggled with the online payment (my ignorance). They phoned me and helped me through the process. I received the confirmation of order & payment immediately. The tracing of the process was very clear - I could see when the courier picked it up and was surprised to see him at my door, 3 days later!! I was very impressed and will use them again.
