I did a search on this phone and apparently a week or so back it was $99 at Coles too. I bought a Samsung Core Prime instead and didn't realise this was cheaper. On the upside it does have NFC which this doesn't. It's a bit tacky and I've only used it to scan opal cards.
I think the Sony is a good deal if you can get it, based on the specs, if not the Core Prime might be a good alternative, albeit slightly more expensive.
On a side note:
Anyone else notice that Woolworths only seems to stock the fixed focus phones whilst Coles ones usually have autofocus???
