Brighton defender Greg Halford has agreed to extend his loan deal from Nottingham Forest until the New Year.
Charlton have extended the loan deal of Arsenal midfielder Francis Coquelin until the end of December.
Moyes kickstarted an outstanding 2012 for the club by bringing in Nikica Jelavic, Darron Gibson and Steven Pienaar during the corresponding window last season.
But that was a rare opportunity for Moyes to spend after being constrained by tight budgets in previous years and the situation is likely to revert to the recent norm this time.
Moyes told BBC Radio Five Live: "Last year we sold (Diniyar) Bilyaletdinov for £5.5million back to Russia and that gave us the opportunity to go and buy.
"We brought in Steven Pienaar on loan from Spurs, we bought Jelavic from Rangers for £5million and Darron Gibson from Man Utd for £500,000.
"We spent the money we got in - that is the way we have tended to work.
"My intention is not to sell anyone this January.
"Because of that what I'll be hoping to do is pick up a couple of loan players or maybe a 'Bosman' if there is anything out there, although at this time of year you rarely get anything of the right quality.
"Normally buying at this time doesn't work, albeit it did for us last year."
One player who could be coming onto the loan market in January, according to reports, is Barcelona and Spain striker David Villa.
When this was mentioned to Moyes, the Scot said: "Yes, I saw that mentioned and I agree.
"If he was loanable and he wanted to join Everton, we'd be more than happy to have him."
Earlier in the day, Moyes was dismissive of fresh speculation concerning the future of left-back Leighton Baines.
A new report has claimed this weekend's opponents Chelsea are now interested in the England international but Moyes said he had not read the report and that is should not be believed.
Benitez, now interim manager at Stamford Bridge, is likely to receive a hostile reception from home fans who will not have forgotten one notorious taunt in 2007.
The Spaniard referred to Everton as one of the Premier League's "smaller teams" after they held Liverpool to a frustrating goalless draw at Anfield.
Overall, Moyes clashed 14 times with Benitez during the latter's six-year spell with the Reds. Everton only managed to win three of those games, all at Goodison.
Moyes said: "It was always tough because Liverpool had a great team.
"It was always hard to get the better of them. They had a tremendous team, and still have.
"I think he (Benitez) always wanted to be in the Premier League. I think he enjoyed his stint here.
"I think, like a lot of people who come to this country, he enjoyed the honesty and the way the Premier League is played.
"I think he has bided his time to get another job."
Benitez has started to turn around the form which prompted Chelsea to sack his predecessor Roberto Di Matteo last month.
The Londoners have won six of their last seven games in all competitions, with the one defeat in that sequence being in the Club World Cup final.
The run has also included an 8-0 thrashing of Aston Villa and seven goals from the often maligned £50million man, Fernando Torres.
Moyes said: "I think it is a great club, they are European champions.
"If you go there you have always got a chance of winning games with the quality and level of players they have got.
"I don't think it is any surprise that Chelsea are winning games.
"He (Benitez) is doing a very good job. He has inherited a really good team, some very good players. You would expect him to win games.
"Fernando Torres is an excellent player.
"I don't know the goings-on at Chelsea and I don't know enough about Fernando Torres to give you any real valued opinion - I just know he has always been a really good player."
Everton, who have finally shaken off their tag of slow starters during the first half of the season, could move to third with a victory.
Moyes said: "We have to beat Chelsea to make that happen and that is a pretty hard task."
