i am looking for a plugin for my wordpress site from which i would be able to change the cost of all the items easily on daily basis. for instance, if the base of price of item 1 and 2 is 20usd and 30 usd, i would just insert the constant of 100 in the plugin and it will add up in the cost making the price of items 120 and 130 respectively. Please, let me know if there are any such plugins available or how can i do it myself. Thank you for your time, your help is really appreciated.
