A few bits in Pennys will be more expensive later in the year.
The owner of the company in the UK Associated British Foods says they're still committed to affordability though.
The fashion chain says it'll make "selective" rises, having managed to avoid most pressures from inflation until now.
It says there will be increased prices across some of their autumn and winter stock.
"Looking further ahead, inflationary pressures are such that we are unable to offset them all with cost savings, and so Primark will implement selective price increases across some of the autumn/winter stock.
"However, we are committed to ensuring our price leadership and everyday affordability, especially in this environment of greater economic uncertainty."
The chain was founded in Dublin, and now has more than 390 stores worldwide. Globally it trades under the name Primark.
