Problem in totaling in Python

I am using python 2.7.13. I had to make a program that inputs a product type and then totals the amount for all the products entered. I tried making one but it isn't working.
there are total 5 types of products that can be entered. Here are their names and prices
bun 0.50
coffee 1.20
cake 1.50
sandwich 2.10
dessert 4.00

What I have tried:

Python

while True:
    item = str(input("Which item would you like to buy?"))
    elif item == 'bun':
        abun = abun + 0.50
        nbun += 1
        continue
    elif item == 'coffee':
        acoffee = acoffee + 1.20
        ncoffee += 1
        continue
    elif item == 'cake':
        acake = acake + 1.50
        ncake += 1
        continue
    elif item == 'sandwich':
        asandwich = asandwich + 2.10
        nsandwich += 1
        continue
    elif item == 'dessert':
        adessert = adessert + 4.00
        ndessert += 1
        continue
    user_input = raw_input('type yes to continue and end to terminate:')
    if user_input == 'end':
        break
    total = abun + acoffee + acake + asandwich + adessert

Hi try this
I assume you are initailising all variables to zero

abun = 0
acoffee=0
acake=0
asandwich=0
adessert=0
nbun=0
ncake=0
ncoffee=0
nsandwich=0
ndessert=0



while True:
    item = raw_input("Which item would you like to buy?")
    if item == 'bun':
        abun = abun + 0.50
        nbun += 1
    elif item == 'coffee':
        acoffee = acoffee + 1.20
        ncoffee += 1
    elif item == 'cake':
        acake = acake + 1.50
        ncake += 1
    elif item == 'sandwich':
        asandwich = asandwich + 2.10
        nsandwich += 1
    elif item == 'dessert':
        adessert = adessert + 4.00
        ndessert += 1
    user_input = raw_input('type yes to continue and end to terminate:')
    if user_input == 'end':
        break
total = abun + acoffee + acake + asandwich + adessert

This works thanks but it still got a problem in there. If I enter three types of items for example three of them are 'bun' the total output should be 1.50 whereas this program gives output 1.00 why is that so
