Usage of ゃ で, when buying countable nouns


> パン屋{や}でパンを買{か}います。

Not sure what ゃ で means here. Noun, ゃ で, noun.

The furigana seems quite small, so this might explain why you _thought_ it
should have been written as

> パン **ゃで**

However,

  1.     1. ゃで 
    2. やで 

are not the same thing. It should actually be 1.2, **やで** , with a regular
sized や. 1.1, with the small や, by itself suggests that there should have been
a [youon](https://en.wikipedia.org/wiki/Y%C5%8Don) before で. For example (not
pertaining to the given image)

  2.     1. かい **しゃ** で
    2. でん **しゃ** で

That is why the title might be considered misleading. With the regular sized
や, it is expected that  
やで could make sense.

In the given image, ～や (～屋, regular や）is a suffix that means _shop_. So _bread
shop_ → _bakery_. In this case, で marks the location where an action takes
place. So the given image reads, more or less, _I buy bread at the bakery._
Two more examples

  3.     1. 本屋｛ほんや｝で本｛ほん｝を買{か｝います。  
_I buy books at the bookstore._

    2. 図書館｛としょかん｝で勉強｛べんきょう｝します。  
_I study at the library._
