I don’t look at Checkout 51 before I go grocery shopping. I just do it after I grocery shop so that I don’t get influenced by their product coupons. A lot of the coupons are for non-produce goods, but for certain things like diapers, it really saves money because I can stack my coupons (e.g. $2.00 print out coupon, and then another $3.00 from Checkout 51 for a total of $5 off the economy box of diapers).
I have only dabbled in drop-shipping before when I had an eCommerce platform 6 years ago or so. I think it is something that you could do on the side, but you would want to do in depth research on the industry you want to get into before setting up shop. It may be a little less passive up front, but over time you could take your hands off the wheel.
Why doesn't my site appear on Google?
The United States Internal Revenue Service categorizes income as active income, passive income, or portfolio income. It defines passive income as only coming from two sources, or "passive activities": rental activity or "trade or business activities in which you do not materially participate." Other financial and government institutions also recognize it as an income obtained as a result of capital growth or in relation to negative gearing. Passive income is usually taxable.
