Also First Orchids on Plymouth-Sorrento Rd. in Apopka is the best place for low priced orchids if you don't mind a lot of them not having tags (i.e. no names). They are a wholesaler to cruise ships and restaurants so will have hundreds of one type of orchid at very low prices. It's a 'cash only' place, though.
I got gift orchids for all my friends and co-workers there for (don't tell them
) $5 each. Nice selection of Catts, Brassavola types and a huge number of Vandas, mostly not in bloom though. All the Vandas I've bought did have tags.
Krull-Smith is also a long-established grower in Apopka. Their prices are a lot higher but they have wonderful named varieties, a lot are their own registered crosses.
