Often these days presenters make reference to the fact that people need to confirm their order within 30 minutes or their item will go back into stock. What are your thoughts on this? What are your experiences? Has something "sold out" only for it to become miraculously available some 30 minutes later? Do you, like me, think it is not polite to hold onto an item for 30 minutes, thereby possibly preventing someone from buying it? Do you ever put something in your basket when you're undecided?
