Bingo, eyes open is the thing. Opportunity is out there, just have to keep looking for it because it doesn't often find you itself. Speaking of opportunity, stores will be having their end of season run outs shortly, so this is more for the fashion sellers, but watch out for on sale bargains to cash in on.
With the change of season, fashion style stores need to flush out old stock and replenish for the new season and that means some sharp bargains if you're in the right place at the right time, with a little cash to spare. This is the time when you can get some quality brands and prices where it's still easy to make a few dollars flipping on eBay.
So keep your eyes open for end of season sales and don't be afraid of tying to sneak a few dollars more off the sale price. Cash talks and retailers love what it says, so use that to your advantage. Also helps if you buy more than one thing as well, multiple purchases will usually secure you a further discount.
