un Sure if rat shack still has push up poles..
But if you go in person..
And you ask if they have 18..20..&.30ft 2-3 sleeve push up masts
( they also likely still have 5 & 10 ft
But after you find they have the size you are looking for..
Then ask, if it is within their current catalog..Because..
( even if they have the same product but with older inventory number..then the older inventory number is not on their current inventory or catalog )
Anything not within their current years inventory catalog (if you speak to the manager(s) are likely to let go for free or stupid cheep price..
I have 10 5 ft
..6 10 ft
... 3 or 4 18/19 ft
... 3 30 ft
push up masts & got them all for free because they were in the store for 2 or more years ( i went to 2 different rat shacks to collect them.. but who cares)
