We usually use our vouchers for a crossing on Eurotunnel for which you get 3 times the value (used to be 4, that's another bug-bear).
This year though, our crossing is included with one of our stays, so I browsed around the Deals site and hit upon Butlins (not somewhere I'd choose to go usually, but thought the kids would enjoy it). Checked prices and for an extra £100 ish, we could go for a long weekend with food included - bargain!
But you don't get the discounts (which are permanently available on the Butlins site it seems to me) when using Clubcard vouchers, so it actually rendered my vouchers as worth less than the original amount, when it should have been 3 times that amount.
AIBU to think that Tesco's who earn like a million pounds a minute are perpetrating a scam of great proportions, or did everyone else know this anyway?
