[Plugin: WooCommerce] Product Bundles – Alternative Plugin?

Hey all,

Is there an alternative to the official Woo Product Bundles/Composite Products plugin?

I need to achieve the following:

1. “bundling” of several existing simple and/or (if possible) variable products into 1, discrete product that a user can add to their cart. This should not involve the user having to add items to the bundle, as per the Grouped Product screen.

2. must manage stock of EXISTING simple products. If I sell an item through the bundle, I want that to be reflected in the stock levels of the simple products

3. discount the bundle – if you buy this bundle that includes 3 simple products, it should be cheaper than if you bought the three simple products individually.

Any tips/suggestions? We’re simply not making enough through our store to justify spending $79.00 or whatever it is on the official bundle plugin.

regards & thanks in advance
