can i set the product price with no Decimal point?

Hi,

Yes. Go in the menu System>Currencies and configure the display settings of your currency accordingly.

Hi,

Yes, the settings of your currency can also allow for that.
Change the "format" from "%i" to "%n" to get the symbol instead of the currency code.
Change the "Symbol precedes positive value" and "Symbol precedes negative value" in order to change the position of the symbol.

Note that the settings are explained in the "help" button you can click on at the top of this edit form. When you want to know more about the settings in a particular page of the HikaShop backend, this help button usually has the answer.

Hi,

Yes, but not with the options available.
You need to add CSS like this:

.hikashop_product_page .hikashop_product_price_full {
    display: flex;
}
.hikashop_product_page .hikashop_product_price_full .hikashop_product_price {
    order: 2;
}
