Nothing takes 'a couple minutes' when you have to sit down and research the five online shops, find if they are approachable, if they will deal with the restrictions of your purchasing department, find out how to submit a query. Many online shops just have a purchasing portal. Find the product, buy it here, pay for it and wait.
So loosely I purchase items at my work from a budget that I am allocated in an organisation that is ultimately responsible to the UK government. I need to justify that the items I am ordering are reasonably priced, and the organisation would really really like to have the goods before any money goes out. That means they want to place an order, receive the goods and and invoice, and then pay the invoice. Many online shops don't want to deal with that. We have accounts set up with many companies, but not all. If I want to buy some reams of 160gsm A4 white card (for example, the other day), that whole process is going to take at least 10 minutes. Some of our suppliers don't sell exactly that. Is 240gsm ok? I've got to go back to the person who wants it (no btw, I had to go find some and take it to them for comparison). More esoteric items are going to take longer. What exactly do I want to order?
So yeah, procurement is simple when you are at home with an amazon account. The items will be here tomorrow!
edit: oh, I didn't mention the free delivery.. a box of white card doesn't get me free delivery. Is there something else I can add onto that? Ok, the order will have to wait..

Unfortunately it sounds like the process is misaligned with the intention. I doubt this mechanism actually works for efficient budgeting and even when it appears to work, it’s probably at the cost of standard quality.
