[FIX] website_sale: strikethrough price

It might happen that a price is strike through in the shopping cart
although it has the same value than the discounted price. This can be
due to differences in decimals smaller than 0.01.

The fix is to apply the same logic than in other places: strike through
if the difference is larger than 0.1.
