I am based in the UK. There is a choice of first or second class as standard at checkout with an option to upgrade for tracked for an extra charge.  Under normal circumstances your order will arrive within 2 weeks.

Outsie the UK the optional of standard international is an untracked method of airmail and depending on the country where you are, the current customs delays, postal delays etc your order can take anything up to 8 weeks to arrive - although most arrive earlier than this.
