Very sticky stuff! I needed 5 tubs of the mortar to complete the job. The mortar lasts well, even once opened so long as you seal the lids back down properly. I found that the tubs also doubled as excellent disposal bins for any other waste I generated from the project. I think there may be a discount on P&P if you spend over a certain amount, so buying the 5 tubs got me that, and I had about 1kg left over, so no real wastage either
