Validating inputs and using conditions seems to continue looping

As shown below, I'm providing the user with an option to spend points, I'm ensuring that the input contains either of 'y yes n no'. If the user would like to spend points he's prompted to select a number which differs the assignment of v, I'm ensuring the input is a number using .isdigit(). If the user wouldn't like to spend points v is simply assigned to 0.0

while True:
    choice = raw_input('\nSpend points?')
    if choice.lower().strip() in "y yes n no".split():
        while True:
            if choice.lower().strip() in "y yes".split():
                c = raw_input('Enter Value 1-6: ')
                if c.isdigit() and int(c) <= 6:
                    if choice.lower().strip() in "y yes".split():
                        if c == '1':
                            v = 0.3
                        if c == '2':
                            v = 0.25
                        if c == '3':
                            v = 0.2
                        if c == '4':
                            v = 0.1
                        if c == '5':
                            v = 0.05
                        if c == '6':
                            v = 0.75
                        break
            if choice.lower().strip() in "n no".split():
                v = 0.0
                break
            else:
                continue
    else:
        continue

    print v

However, although the code works fine, after v seems to be printed successfully, the code will continue looping back to 'Would you like to spend credits?'

I believe the problem lies with my break statement, but I'm not sure where it's supposed to go.
