It's always difficult to sift the wheat from the chaff when it comes to online software. I signed up to Sku Grid at a time when it was having endless problems. Whilst the software may be one of the cheapest on the markets the amount it cost me due to errors meant that I unfortunately lost more money than I made. I'd strongly spend a little extra and go for something along the lines of Profit Scraper or PriceMatik - Both seem to be very reliable. I've spent some time reviewing both here: www.thriftypence.com/pricematik-review/. Hope this is useful and may save you a few mistakes (and pennies) on your journey to setting up a drop shipping business.
