Roll then stroll

Been using this a long while now works fine cuts clean up in half..Anyone found anything cheaper/better.. I roll this for the perimeter and walkways and dust sheet the middles just wondered cos I ran out today and have to rebuy..Always hurts..
I use 3 types. 100m clear roll from ebay £25. Its OK. Not as thick plastic as the better stuff and not as sticky but sometimes that's works great. Indasa yellow masking 50mm wide from ebay at £2.20 ish a roll around edges. I used the red indasa to mark for safety lines and if I need a better stick to carpet ect. The one stop plastering shop rolls of plastic is brilliant and good quality. Packexe is market leader and buy online for best price. I can put links up here if needed
