At the moment the price range widget does not show the products if they have a variation price that fits the range. the sql query needs redone.
also when using the All filter a notice is visible:
Notice: Undefined offset: 1 in D:\wamp\www\testwp\wp-content\plugins\wp-e-commerce\wpsc-components\theme-engine-v1\widgets\price_range_widget.php on line 152
Price range widget checks variations too
Fix for #800
strpos condition is changed
We're not quite there yet on this, punting pending further revisions.
Just an update. I believe there is an issue with the retrieval on products with big prices too.
Got a store with products prices like $87,000.00 and higher and when you click the widget to show products Over $13,500.00 it only lists like 6 products while there are lots more.
A review of the SQL would be in order i think
