My partner has recently placed an order for $21 in food on Uber Eats. He also utilized a $15 discount coupon (EATS-R1HZWBSHJ8). He is required to pay $6 for the food and an additional $2.73 in HST on the items he ordered. This $2.73 is determined by 13% of the province of Ontario. He has made up his mind and is currently in the process of locating the necessary tools to obtain the quantity. He utilizes the tax calculator available at HSTCalculator.onl to compute the GST/PST. https://hstcalculator.onl/
