Tesco's item limit

Having finally finished uni and got home 'n' that me and Eden went to store of sticky wonder to start stocking up for our first session in a while. Went to the counter with a couple of bags of cake mix, some ice cream sauce and a whole load of budget angel delight mix...
Checkout guy: "Erm, how may of these are there?"
Us: "20"
CG: "We have a bulk buy policy, you can only buy 5 at once... are you having a party?"
Us: "Er... yeah."
CG: "I'll check with the supervisor"
*brief wait*
Supervisor: "We have a bulk buy policy so you can only buy 5 of one item at once... if you want more you should place an order with customer services beforehand, then you can collect them"
Us: "Oh. right"
*mildly awkward silence*
Supervisor: "Tell you what, just put them through this time, but make sure you order in in the future"
Not sure if anyone else has encountered this problem, I know we hadn't until now. Ordering in isn't so hard, and we were stocking up a bit in advance so it wouldn't have been so bad if they didn't let us buy it all, but this is a heads-up for anyone before they go for a spontaneous splosh shop.
