Dunelm had brabantia ground spikes reduced to £3 about a week ago instore, couldnt find them online though
Tesco were doing the 45m Minky's for £22.50 - clearance only. I got a ground spike off amazon for under £6 - there are different sizes, so make sure to measure the diameter of your dryer before buying a spike
My garden is concrete underneath about 5 inches of soil so we bought a parasol base from IKEA.
B and Q have ground spikes for £7.
You need a spear, B&Q used to sell them for £13! JL has them for about £8. anyway I still think they’re over priced for what they are so better dig a hole in the ground :D
