Pulis took over at Selhurst Park in November since when the Eagles have won three games to move outside the bottom three.
But Pulis knows that he will have to enjoy some good fortune as well as shrewd forward-planning in January if he is to secure survival at Selhurst Park this spring.
"Every club I've been at, I don't think anyone can decry me spending too much and not giving them a return on their money," he said.
"I have always prided myself in that respect and if I bring players in they will be coming in to help us initially stay in the Premier League.
"If they are older players you keep the value by staying in the Premier League or they are young and they actually gain value.
"At Stoke if you look at Ryan Shawcross, Asmir Begovic, Marc Wilson and Steven Nzonzi - they have all maintained Premier League football for Stoke City.
"Their value now compared to what we paid at the time would have gone through the roof - if we could do the same at this football club then I would be doing somersaults.
"I'm hoping and praying that one or two things will drop for us. Both in terms of players who are not in the squad or around the squad, moving them on and letting them play. That might leave us a little room to manoeuvre and bring a few in."
With yet another 'key game' looming in the shape of Norwich City on New Year's Day, Pulis is refusing to get too carried away with their recent successes.
"I'm just concerned about the next game and the next game," he said.
"If you pat yourself on the back for having a good performance this game will kick you up the backside but if you get down and depressed you drag other people down with you.
"You have to be upbeat and positive and though it affects you, you have to get over it as soon as you can - whether that is a good or a bad performance.
"When I say I'm never happy - I think you can never be happy with your lot. If you are driven then you strive to improve, you mustn't confuse that for not being happy. In respect of striving to get better all the time that is who I am.
"It is the New Year, it is not the end of the season. The most important thing is that we stay focused and that we prepare properly for Wednesday and the next game, until the end of the season or until we get the points to keep us in the Premier League."
