I can’t believe I’m even replying to this.
You would go to Ebay for the following reasons:
1) So you don’t have to go to “Business Depot”. You can just order it with 3 clicks of a mouse and it gets delivered to your door 2 days later.
2) I don’t know about Canada, but in Australia, shit is usually cheaper when you buy via internet sites (new or used). I don’t waste my time going to stores to buy simple goods like a BAII Plus, it’s not like I need to try it on for size.
3) Dec 2011 CFA results just came through and a bunch of failed candidates who have decided CFA is not for them will put their calculators for sale on Ebay. I bought mine for $10 on Ebay, new on Ebay it’s like $60, new in a store add another $15 at least.
