Hi guys. i have a client who I a building a store for. She would like to know if she can sell some of her items in bulk. for example her product page may consist of almonds and if I am able to add a drop down menu of grams and the price changes based on how many grams i select. I have come across some apps that can do this however they are all paid apps and she does not want to spend any money on apps. I believe i can do this with coding however i need some help with this.
