Fischers fill fix - cheaper alternative?

[callutwice]

Hi, I tried fixing holes in a plastered wall, where a shelf had fallen down, using Fischer's Fill Fix ("liquid plug"). I could then screw the shelf back up directly, without a plug, and it holds really well. However, it's very EXPENSIVE. Around 220 SEK per tube, which doesn't go far if the holes are large! Is there a cheap alternative? Do you think, for example, this one can work similarly? https://www.clasohlson.com/se/Repair-Putty-Universal-Loctite/34-9016
