Hi,
The shipping restriction does not work.
Ah yes that's right ; there is no code for that in the plugin.
For buy some products with points and other with EUR (all togheter) i give up! 
There are too many possibilities and too many questions for a feature that you can write in a single small line.
Does a product which can be bought by points can be bought with some real money ?
If the user want to use his points to buy some products and they are several different rules (for different products) how does the plugins should read ? Depending that one could ask for a partial sum of the user points and the other won't have enough points for his rules if the first one use the points... Does the priorities should really count ? Maybe the user could choose which products ? But if they are different rules for the same product (one for the product, another for the category, or maybe two for the products but with different restrictions) ?!
It is definitively not something easy to implement and you can be sure that I passed a lot of hours thinking about it ; writing ideas on paper ; discarding some, tearing other...
So yes, it's already in my TODO list for HikaPoints, with a lot of other funny features.
Regards,
