If you run the store sync, and recieve the following error:
<b>Fatal error</b>: Allowed memory size of XXX bytes exhausted (tried to allocate XXX bytes) in <b>/home/superbadger/public_html/yourwebsite.com/wp-content/plugins/woocommerce/includes/api/v2/class-wc-api-json-handler.php</b> on line <b>76</b><br />
It means that there isn't enough PHP memory. The memory limit for a script should be set higher on your server.
Solution: You should increase the PHP memory on your WP. Similar case has been covered here on this WordPress forum:
