Not due to the market only. But due to prices given by companies : Blackberry, LG, Dell, etc.

I bought my Nexus 4 for R$1.699 and 6 months later it was for R$800. No negociations were possible between me and LG to refund me. It was my problem, as I wanted to have a Nexus 4 in the beginning of its launch in Brazil. Who waited for some months had the advantage of paying less.

No negociations between me and Dell (I use Dell notebooks for more than 13 years) were possible, I've tried by phone some years ago. I've lost the excellent promotional price during one week. My decision, my responsibility.

Well, so I would drop buying from almost all the companies I'm used to : Apple (indication for my family), Asus, Dell, LG, Samsung, etc. All of them have had cases of oscillating prices where I or my family have paid more at some moment and some time later it was lower. It happens.

By the way, I've paid for my 1st Jolla via Amazon.UK approx. R$2,000 (US$820, EUR642 currently) with international shipping, Brazilian import taxes,etc. It was my decision to buy it. Period. I don't compare with Indian or European prices for Jolla smartphone, where I could pay a lot less. My reality is that I live in Brazil. I'll not blame Jolla for this fact.

PS: I've had luck when buying Psion Revo+, Nokia N810, Nokia N900, etc at the minimum historical price where I were living at the time. Sometimes we have luck with prices, sometimes not.
