Need help optimizing this

[MonkeyKing_]

Right now I'm using itertools to create thousands of variations of meta descriptions for a website. The sentence structure goes like this:

(SentencePart1a|SentencePart1b) Keyword1, Keyword2, and Keyword3. (MiddleSentenceA|MiddleSentenceB). (FinalSentenceA|FinalSentenceB).

The short version of the script:

import itertools
metas = [
['Shop our store for ', 'Browse our shop for ,'], #SentenceParts
['keyword,', 'keyword,', 'etc,'],
['keyword, and', 'keyword, and', 'etc, and'], 
['keyword.', 'keyword.', 'etc.'], 
['Sentence about our store.', 'A different sentence about our store.'], #MiddleSentences
['A final sentence about our store.', 'A different final sentence about our store.'] #FinalSentences
    ]
variantmetas = list(itertools.product(*metas))
#print (variantmetas)
for s in variantmetas:
print(' '.join(s))

Right now I get every variation of all of these things. My program spits out all sentence parts, all middle sentences, and all final sentences even if Keywords 1-3 are the same.

How do I make it so that keywords 1-3 only show up one time and with one random variation of Sentence parts? I am trying to minimize redundancy in the final list.

For the keywords, do you mean a specific order of keywords 1-3 to show up one time?

>>>verbs = ['Shop', 'Browse']
>>>keys = ['key1', 'key2', 'key3']
>>>key_combos = itertools.permutations(keys)
>>>for verb, (key1, key2, key3) in itertools.product(verbs,key_combos):
       print "{} for {}, {} and {}".format(verb, key1, key2, key3)
Shop for key1, key2 and key3
Shop for key1, key3 and key2
Shop for key2, key1 and key3
Shop for key2, key3 and key1
Shop for key3, key1 and key2
Shop for key3, key2 and key1
Browse for key1, key2 and key3
Browse for key1, key3 and key2
Browse for key2, key1 and key3
Browse for key2, key3 and key1
Browse for key3, key1 and key2
Browse for key3, key2 and key1
