Bedding plants

I'm absolutely rubbish at growing geraniums,  busy lizzy or begonias so I usually buy some in.  Being a bit tight fisted I look for bargains in mini plugs and bring them on in the gh.  Year after year I've gone against my better judgement and bought from T&M or VM each time ending up in an argument over late delivery,  poor  quality,  etc.  Yes they replace and yes they refund, but it's getting beyond a joke.   My question is, next year, where can I get reasonably priced mini plug bedding plants that are reliable.  I've said to myself I will not use T&M again.
