I too bought bulbs end of season (november) and planted up, five to a small pot. Kept in a cold greenhouse but watered after planting they all flowered and were planted out whilst in flower, so that I had them where the spaces were. The single ones self seed, but the double ones need to be split after 2 or 3 years.
grown this way you can see where those from previous years are and fill in the gaps where you want them, also you won't haver to wait until next year to buy in the green, thereby missing next springs flowering. Pots in flower in the garden centre are always expensive, and probably the same bulbs you could be planting up for yourself!
