Is there on other way to pay contact lenses apart from direct debit?

[Goochland]

For example, at Specsavers. If my contact lenses were 10 a month, is there no other way to pay apart from direct debit? I'm 16 you see and would like contact lenses before September. I asked my mum but for some reason she doesn't seem too keen. Could you help me please? Thanks in advance!

Why don't you stick to get them on Specsavers ? You can buy them from online stores which is cheaper and no need for a direct debit if you have a copy of your prescription . Also you can buy them in bulk .It is the most economical way for people who want to save money .
