Well, first of all. Those people making millions are most often using more than 1 instance of Abrosia across multiple IPs and with different accounts, then later transferring the wealth.
Second, shops take time to restock... sometimes you won't see items restock for 30 minutes to an hour.
Third, you might need to adjust your buy time, since you are not an Advanced member, you won't be able to adjust really.. anything. Consider buying Advanced if you want to buy faster (that is if it already isn't fast enough) Go to Tiki Tack (Shop 21) and set your minimum profit to say... 100 and buy an item. Note your buy time in the log beside the item. You want that to be probably just be over 2000-3000 if you are first starting to buy, just to show a bit of realism. As you go on, try and lower that to a little bit under 2000 (1500-2000) and read around on a safe buy time around the forums. Everyone is different.
Now, what shop are you buying in? Try and avoid shops such as Stamps, Magic, Merifoods and all the high value shops as much as you can... you will get frozen in a heartbeat with one small screw-up. I would recommend Food, Spooky Food, Toys or whichever shop you want if you are > 4 months.
For starting cash, it all depends on the shop you're in. For most shops, a couple hundred thousands Neopoints is probably fine.
If you have any other questions, just message me.
