I use your plugin quite often on a number of French websites.
I have noticed an issue affecting these French sites.
When setting a product bundle price manually (i.e., not using the automatic method), entering a price with a comma causes the price to default to 0.
In France, prices are formatted like this: 43,3€.
If we set the bundle price to 43€, it displays correctly;
however, if I enter 43,30€,
the price automatically switches to zero...
I urge you to fix this issue, as it leads to a number of bugs...
