Price shown online was different from the price charged at checkout

Advertising a price that differs from what is actually charged can amount to a misleading commercial practice, and traders operating in Malta are subject to consumer protection standards on price transparency connected to the Consumer Affairs Act, Chapter 378 of the Laws of Malta, which is largely aligned with EU consumer rules on unfair commercial practices. Take a screenshot or archived copy of the listing showing the original advertised price if you still have access to it, along with your payment confirmation showing the higher amount actually charged. Contact the seller in writing, point out the discrepancy, and request a refund of the difference between the advertised and charged price. If the seller refuses or ignores you, report the practice to the Malta Competition and Consumer Affairs Authority (MCCAA), which monitors misleading pricing, and consider a claim through the Consumer Claims Tribunal to recover the overcharged amount.
