Hi Jack,
Their have made changes since oct 17
I'll try to explain:
In oct 17 their prices are show in DOP Pesos (not USD, 1USD = 40DOP) (primary currency=DOP).
In nov 12 their prices are show in USD and DOP (both) (primary currency=USD).
now their "product_price" is for USD currency (works fine for prices under 999) (primary currency=USD).
now their "product_alt_price" is for DOP currency (works fine for prices under 999, but not works for prices over 999) (primary currency=USD).
But in my store the primary currency is DOP Pesos not USD. (remember 1USD = 40DOP)
When i try to compare with <span id="product_alt_price">(.*)</span> dont work because USD500 = DOP20,000 (primary currency showed in my store).
Hope you understand me.
Thanks Jack
