why is offer R490 here and when you click on it it goes to R563?

Based on the search results, it seems the Belkin Boostcharge Flex USB-A cable with Lightning connector for iPad and iPad Pro shows a price of R348 when viewed in the PriceCheck search results, but may show a higher price of R563 when clicked through to the retailer's website to purchase. This sometimes occurs when the price displayed in price comparison search results is an introductory or limited time offer price that is no longer valid once on the retailer's site. The price can then revert to the standard retail price, which may be higher. Always best to check the price is still the same as quoted before completing your purchase. Please let me know if you have any other questions!

Based on your search for an "ACER ASPIRE AS10D41 BATTERY", I would recommend either of the first two options listed. Both are replacement batteries specifically listed as compatible with the Acer Aspire AS10D41 model. The first option for R599 and second option for R490 would give you a high capacity long-lasting battery to power your Aspire laptop. I hope this helps in finding a good replacement - let me know if you need any other details!
