I have bought from Calumet previously (Photographic Show NEC) and as they are fairly local I decided to purchase a couple of lenses from their Manchester store. One lens had to be brought from another of their stores and I collected after a phone call to confirm my order was ready for collection. However I was made to feel like I was a potential thief, staff appeared to be extremely suspicious of my presence in the store and were reluctant to let me view the lenses before I had paid for them. This put paid to me making further purchases, I am sure they are aware competition is extremely competitive especially with the use of the Internet, it was only due to time limitations that I had to purchase from this store. Due to my recent experience I will only use Calumet as a last resort. Michael J Pearson.
