Groupees' bundles tend to hit and miss, and the awkwardly-named Build A Be Mine Bundle is no exception. Effectively you can pick two games for $1, then stack on extra games at an increasing discount, but the selection is niche to say the least.
Which is just how I like it. Personally I'd suggest grabbing zany board game 100% Orange Juice and puzzly RPG 99 Spirits, which are both a steal at approximately 60p. Thanks to jaystan @ HUKD!
