Re online shopping, and especially ebay, it also requires one to “pay attention to prevailing prices” to avoid being ripped off from one’s own ignorance.
I was just in the market for a garden sprayer. One product of interest was on ebay, shipping included for $82.99 and also at $133.90. Bunnings has the same product for $41. Another sprayer was $179 at Bunnings as compared to $335 from the ebay merchant. (I bought a different product on ebay that was well reviewed, priced OK, the seller had high satisfaction and volume and was responsive to contact).
FWIW one selling technique on ebay is to list a product at a high price a few times, and also at a lower price making the lower price look like a real deal, but it might or might not be. YMMV.
