What our customers say
I have ordered goods a few times now (6 in fact) over the past couple of years and this is the only company I like to use. The website is excellent; the customer service and dispatch speed are also very good. Prices not always the best but often free shipping makes up for that.
From Hamilton
In regards to delivery I was amazed, expecting 2-3 days and bam 2 hours later it was in my hands. Ok so it was in the same city but I have had orders from other companies in the next suburb that have taken 5 days :). As soon as I get some more money I will be back.
